The Grand Staircase is one of the architectural highlights of the Palace of Knossos. The sections below cover what it is, why it is an engineering marvel, where it leads, whether it is reconstructed, when it was found and how to see it.
What is the Grand Staircase at Knossos?
The Grand Staircase is a monumental stone stairway in the east wing of Knossos, descending through the storeys of the royal apartments around a central light-well.
The Grand Staircase is one of the most impressive architectural features of the palace of Knossos, a monumental stone stairway located in the east wing, where the royal apartments were built into the slope of the hill. It descended through the storeys of the palace, with flights of broad stone steps turning around a central open space, connecting the different levels of this multi-storey part of the building.
The architects wound the staircase around a light-well, an open shaft that brought daylight and air deep into the heart of the building. Substantial parts of it survive, making it one of the best places to appreciate the scale, sophistication and multi-storey nature of Minoan palace architecture. It is rightly regarded as a highlight of any visit. Our guide to the Knossos layout covers the royal apartments.
The staircase occupied the eastern slope of the palace mound, where the ground fell away sharply toward the Kairatos stream. The royal apartments there rose four storeys, and the flights climbed and descended around the shaft on each level, flanked by colonnades that repeated from storey to storey. The steps were cut from gypsum, a soft local stone that the Minoans quarried near the site and dressed into broad, shallow treads for an easy climb. This arrangement made the east wing the tallest surviving part of Knossos and the clearest evidence that the Minoans built vertically, not just across the ground. The next section covers why it is an engineering marvel.
Why is the Grand Staircase an engineering marvel?
The Grand Staircase is an engineering marvel because it solved the challenge of building multi-storey royal apartments into a hillside, using a light-well to bring daylight and air to the interior.
The Grand Staircase is celebrated as a feat of Minoan engineering because of the sophistication with which it solved a real architectural challenge: building grand, multi-storey royal apartments into a sloping hillside while keeping the deep interior of the building light and airy. The result demonstrates an advanced understanding of structure, space and construction far ahead of its time.
The key innovation was the light-well, the open vertical shaft around which the staircase was arranged. This brought daylight and fresh air down through the storeys into rooms that would otherwise have been dark, a clever solution to lighting and ventilating a large, multi-level building. Combined with columns, porticoes and fine stonework, the Grand Staircase showcases the engineering and design skill of the Minoans. Our guide to the key features of Knossos Palace covers the engineering.
The colonnades doubled as structure and as light control. Columns repeated on each storey carried the flights above and framed the open shaft, so daylight fell in graded steps from the top of the well down to the lowest rooms. The Minoans tapered these columns, wider at the top than at the base, a signature form that also appears in the throne room and the north entrance. The builders paired this with the palace drainage and water systems, giving the east wing both light and clean interiors.
The light-well also managed heat and rain, not just brightness. In the Cretan summer the open shaft drew warm air upward and pulled cooler air through the rooms below, an early form of passive ventilation. In winter the same shaft admitted low sunlight into the interior, while a drain at its base carried off rainwater to the palace channels. The staircase therefore works as a single machine for living: it moves people between four floors, ventilates them and lights them at the same time. The next section covers where the staircase leads.
Where does the Grand Staircase lead?
The Grand Staircase leads to the royal apartments in the east wing of Knossos, including the King’s Hall, or Hall of the Double Axes, and the Queen’s Megaron with its dolphin fresco.
The Grand Staircase leads down into the royal apartments, the private residential quarters of the palace built into the east wing and the hillside. It was the grand, dignified route connecting the different levels of this part of the palace, where the rulers of Knossos are thought to have lived, and descending it today takes you into the heart of the domestic palace.
The rooms reached via the staircase include the grand King’s Hall, also known as the Hall of the Double Axes after the sacred labrys symbols carved into its walls, and the elegant Queen’s Megaron, famous for its dolphin fresco and its adjoining bathroom. These fine rooms, with their light-wells, columns and frescoes, give a vivid sense of the comfort of Minoan elite life. Our guide to the Queen’s Megaron covers the royal quarters.
The Hall of the Double Axes takes its name from the labrys, the double axe cut as a mason’s mark into its gypsum blocks and treated as a sacred emblem across Minoan Crete. The hall opened onto its own light-wells and a portico, so it stayed cool in the Cretan summer and bright in winter. A wooden throne and canopy once stood inside, and Evans reconstructed a version of them to show how the room was used.
The adjoining Queen’s Megaron shows a lighter, domestic scale, and its bathroom held a clay tub set beside a drainage channel. The dolphin fresco on its wall, painted in blue and ochre, is the emblem most visitors remember from this part of the palace. The staircase tied these private rooms to the upper storeys and the wider palace, so it read as the formal approach to the most guarded part of Knossos. The next section covers whether the staircase is reconstructed.
Is the Grand Staircase original or reconstructed?
The Grand Staircase is partly original and partly reconstructed. Substantial original stonework survives, but Sir Arthur Evans restored and rebuilt parts of it, including upper flights and supports, in concrete.
The Grand Staircase as visitors see it today is a blend of genuine Minoan remains and modern reconstruction. A substantial amount of the original stonework survives, including original steps and structure, which is part of what makes the staircase so impressive, as it is one of the better-preserved features of the palace.
Sir Arthur Evans, who excavated and controversially restored Knossos, reconstructed and consolidated parts of the staircase, including upper flights, columns and supports, using reinforced concrete, both to preserve the fragile remains and to recreate the multi-storey effect. This makes the feature vivid and easy to appreciate but means that not everything you see is original Minoan work. Our guide to Sir Arthur Evans and Knossos covers the restorations.
The lower flights and the surrounding gypsum walls preserve genuine Minoan work, while the upper storeys and their columns are largely Evans’s concrete recreation, tinted and shaped to suggest the timber originals. The original Minoan columns were wooden, so they rotted away entirely, and Evans cast his replacements in concrete to stand in for them permanently. He made this choice to hold up the collapsing east wing and to let visitors read the vertical form that excavation alone could not show. The result is a feature that is real at its base and interpretive at its top, and knowing that division sharpens how you look at the flights. The next section covers when the staircase was discovered.
When was the Grand Staircase discovered?
The Grand Staircase was discovered by Sir Arthur Evans during his excavation of Knossos in the summer of the year nineteen hundred and one of our era, early in the campaign that uncovered the east wing.
Sir Arthur Evans found the Grand Staircase in the summer of the year nineteen hundred and one of our era, during the second season of his excavation of the palace. His teams dug into the east slope of the mound and struck the collapsed flights of the royal apartments, one of the most dramatic finds of the whole campaign at Knossos. Evans had begun clearing the site only the year before, so the staircase came to light while the shape of the palace was still emerging from the earth and its full extent was not yet known.
The discovery presented Evans with an immediate engineering problem as well as a spectacular find. The upper storeys had fallen inward, and the fragile gypsum steps needed support before the deeper rooms could be cleared. Evans propped the flights, then rebuilt the missing storeys in stages over the following years, turning a buried ruin into the standing structure that visitors read today. Our guide to the Palace of Knossos covers the excavation history.
The find confirmed that the east wing had risen four storeys, a scale that reshaped how scholars pictured Minoan architecture. Earlier reconstructions imagined low, single-level courts, and the tall stairway forced a rethink of Bronze Age building on Crete. Evans described the moment of clearing the flights as one of the high points of his work at Knossos, and the staircase became the emblem of his vision of a multi-storey palace. His draughtsmen recorded each surviving step and column base before any concrete went in, so the rebuild followed measured evidence rather than guesswork. The next section covers how to see the staircase.
Can you see the Grand Staircase at Knossos today?
Yes, you can see the Grand Staircase as part of a visit to Knossos, in the royal apartments of the east wing, though it is viewed from designated points rather than walked.
The Grand Staircase is one of the highlights you can see on a visit to Knossos, located in the royal apartments of the east wing, reached as you explore that part of the palace. Its surviving flights, light-well and reconstructed upper storeys give a powerful impression of the scale of the multi-storey Minoan palace. It ranks with the throne room and the north entrance among the features visitors remember most, and it is one of the most memorable structures at the whole site.
The staircase itself has been closed to visitors since the nineteen-nineties of our era, on account of stability and damage concerns affecting the fragile flights. Visitors now view it from designated points rather than walking its full length, and the vantage points give an excellent view of the structure. A guide or audio guide helps you find the staircase and understand what is original and what was reconstructed. Visiting early in the day avoids the crowds at the royal apartments, and the shade of the east wing makes it a welcome stop in the summer heat. Plan your visit through our Palace of Knossos guide.
The staircase sits in the east wing, so it comes late in the standard visitor route that starts at the west court and the throne room. Reaching it means crossing the central court and descending toward the Kairatos slope, and the walk itself shows how the palace stepped down the hillside. Signboards at the viewing points name the King’s Hall, the Queen’s Megaron and the light-well, so you can read the layout even without walking the flights. Morning light falls directly into the shaft, which is the best time to photograph the surviving steps and the reconstructed columns above them. Allow a short pause here, because this is the one spot where the four-storey scale of Knossos becomes plain to the eye.
Standing before the Grand Staircase, you grasp something that plans and photographs struggle to convey: the sheer verticality and ambition of Knossos. This was not a single-storey ceremonial ground but a tall, light-filled royal residence climbing the hillside, and the staircase was its spine. Its stone flights, its open light-well and its reconstructed upper storeys make it the clearest place at the whole site to feel the confidence of the Minoan builders. For many visitors it is the moment Knossos stops being a field of low walls and becomes, in the imagination, the grand multi-storey palace it once was.
Frequently Asked Questions
What is the Grand Staircase at Knossos?
The Grand Staircase is a monumental stone stairway in the east wing of the palace of Knossos, one of the most impressive surviving features of the Minoan palace. It descended through the storeys of the royal apartments, built into the slope of the hill, with broad flights of stone steps turning around a central light-well that brought daylight and air deep into the building. It is celebrated as a feat of Minoan engineering, demonstrating an advanced understanding of structure, lighting and construction. The staircase led down into the private royal quarters, including the King’s Hall and the Queen’s Megaron. Substantial original stonework survives, though parts were reconstructed by Sir Arthur Evans, and it remains a highlight of any visit to Knossos.
Why is the Grand Staircase important?
The Grand Staircase is important because it is one of the finest examples of Minoan architectural and engineering skill, and one of the best-preserved features at Knossos. It solved the challenge of building grand, multi-storey royal apartments into a hillside while keeping the deep interior light and airy, using a clever light-well, an open shaft, to bring daylight and ventilation down through the storeys. This shows the Minoans’ advanced understanding of structure, space and lighting, far ahead of its time. The staircase also led to the heart of the royal apartments, including the King’s Hall and the Queen’s Megaron, so it gives a vivid sense of the scale and comfort of Minoan elite life, making it a highlight of a visit to the palace.
Was the Grand Staircase at Knossos reconstructed?
Yes, the Grand Staircase was partly reconstructed, like much of Knossos. A substantial amount of the original Minoan stonework survives, including original steps and structure, making it one of the better-preserved features of the palace. Sir Arthur Evans, who excavated and controversially restored Knossos, also reconstructed and consolidated parts of it, including upper flights, columns and supports, using reinforced concrete, both to preserve the fragile remains and to recreate the multi-storey effect. This makes the staircase vivid and easy to appreciate but means that not everything visible is original Minoan work. Knowing the blend of genuine remains and modern reconstruction adds to the interest of seeing this remarkable feature.
How many storeys did the Grand Staircase serve?
The Grand Staircase served the four storeys of the royal apartments in the east wing of Knossos. The Minoans built these apartments into the steep eastern slope of the palace mound, so the wing rose four floors from the lowest rooms to the top of the light-well. The staircase climbed and descended around the central open shaft on each level, with colonnades of columns repeating from storey to storey to carry the flights above. This vertical arrangement made the east wing the tallest surviving part of the palace and the strongest evidence that the Minoans built upward, not only across the ground. Sir Arthur Evans rebuilt the upper floors in reinforced concrete to make this four-storey form visible to visitors today.
Can you walk on the Grand Staircase at Knossos?
No, you cannot walk on the Grand Staircase today. It has been closed to visitors since the nineteen-nineties of our era on account of stability and damage concerns. The genuine Minoan flights are fragile, and long foot traffic combined with the age of the stonework made access onto the steps a risk to the structure. Visitors now view the staircase from designated points beside the royal apartments in the east wing. These vantage points give an excellent view of the flights, the light-well and the reconstructed upper storeys. A guide or audio guide helps you find the best viewing spots and understand what is original Minoan work and what Sir Arthur Evans reconstructed.
