Hagia Sophia Floor Plan & Layout Guide
Navigate every level of Hagia Sophia with our detailed floor plan guide. From the narthex to the apse, from the ground floor to the upper galleries β know exactly where to go and what to see.
Building Overview
Hagia Sophia's floor plan spans an area of roughly 82 meters long and 73 meters wide. The central dome rises 55.6 meters above the floor with a diameter of 31.24 meters, creating one of the largest enclosed spaces of the ancient world. The layout follows a modified basilica plan with a dominant central dome supported by pendentives β an engineering breakthrough of the 6th century.

Ground Floor Layout
The ground floor contains the primary spaces of Hagia Sophia β the central nave, flanking aisles, narthex vestibules, and the eastern apse. Here is each area and its position on the floor plan.
Main Entrance (Imperial Door)
WestThe grand Imperial Door served as the emperor's private entrance. Above it hangs a 9th-century mosaic of Christ enthroned. Today all visitors pass through this doorway to enter the main nave.
Narthex & Inner Narthex
West β Entry VestibulesTwo long vestibules stretch across the full width of the building. The outer narthex leads into the inner narthex (esonarthex), whose barrel-vaulted ceilings still bear original 6th-century gold mosaic decoration.
Central Nave
Center β Under the DomeThe main prayer space stretches beneath the 55.6-meter-high dome. The Omphalion, a large circular marble panel in the floor, marks the spot where Byzantine emperors were crowned. This is the heart of Hagia Sophia.
Apse & Mihrab
East End β Direction of MeccaThe semi-circular apse holds a golden mosaic of the Virgin and Child. Below it sits the mihrab, angled slightly from the apse because the building does not face Mecca precisely. The minbar (pulpit) stands nearby.
North & South Aisles
Flanking the NaveColonnaded aisles run along both sides of the central nave, separated by rows of verde antico and porphyry columns. These aisles provide a quieter perspective and good angles for photographing the dome above.
Weeping Column
Northwest β Near EntranceThis copper-clad pillar has a thumb-sized hole worn smooth by centuries of visitors. Legend says inserting your thumb and feeling moisture grants a wish. It is associated with St. Gregory the Miracle Worker.
Sultan's Lodge (Hunkar Mahfili)
Southeast CornerAn elevated gilded platform added by the Fossati brothers in the 19th century. The Sultan used this latticed enclosure for private worship during Friday prayers, set apart from the congregation below.
Upper Gallery Layout
The upper gallery wraps around three sides of the nave and is accessed via a stone ramp at the north end. A separate ticket (25 EUR for foreign visitors) is required.
South Gallery
Deesis Mosaic, Empress Zoe & Comnenus MosaicsThe south gallery houses Hagia Sophia's most celebrated Byzantine mosaics. The 13th-century Deesis mosaic is considered a masterpiece of Byzantine art. Nearby, the Empress Zoe and Comnenus mosaics depict imperial portraits.
North Gallery
Less Visited β Structural ViewsThe quieter north gallery offers excellent views of the building's structural engineering, including the massive piers and buttress arches that support the dome. Fewer visitors come here, making it ideal for contemplation.
West Gallery
Panoramic Dome ViewsThe west gallery provides the most dramatic frontal view of the dome and half-domes cascading down toward the apse. This is the best vantage point for appreciating the full scale and geometry of the interior.
Suggested Walking Route
Enter through the Imperial Door on the west side and pause in the inner narthex to see the 6th-century gold mosaics on the barrel-vaulted ceilings.
Walk straight ahead into the central nave and stand on the Omphalion. Look up to take in the full dome and ring of 40 windows.
Head east toward the apse to see the Virgin and Child mosaic and the mihrab below it.
Circle to the northwest corner to visit the Weeping Column, then explore the north and south aisles.
Walk to the southeast corner to see the Sultan's Lodge (Hunkar Mahfili).
Take the stone ramp at the north end up to the upper gallery. Visit the south gallery first for the Deesis, Empress Zoe, and Comnenus mosaics.
Cross to the west gallery for the best panoramic view of the dome, then exit via the north gallery.
