Bayezid II Mosque

Mosque · BeyazıtIstanbul,Türkiye

The oldest imperial mosque still standing in Istanbul, finished in 1505 on the old Byzantine forum, its dome plan the one Sinan would later refine.

Bayezid II Mosque is the oldest imperial mosque complex still standing in Istanbul, at the heart of a working quarter between the Grand Bazaar's gates and the university. You enter through a colonnaded courtyard where the ablution fountain murmurs under its own small dome, ringed by columns of porphyry and green-veined marble salvaged from older ruins. Inside, daylight drops from a ring of windows onto stone worn smooth by five centuries of feet. Sultan Bayezid II raised it between 1500 and 1505. Its builders looked along the peninsula's ridge to Hagia Sophia and crowned the prayer hall with a central dome braced by two half-domes, the scheme Sinan would later refine into the skyline we know. The square outside was once the grandest forum of Byzantine Constantinople, and pigeons wheel over it all day. The old secondhand-book market opens off a gate on the western side. It remains an ordinary neighbourhood mosque, busy at every call to prayer.

Worth knowing

Good to know

Each minaret tells its own story — the two shafts, set unusually far apart, carry different geometric patterns of terracotta-red and pale stone; back into the square to frame both in one glance.
No two courtyard columns match — look along the colonnade and you'll see shafts of different stone and girth standing together, their bases and capitals quietly resized so the mismatch settles into one deliberate set.
Look down before you look up — carved marble drums from the Roman Forum of Theodosius lie at the square's edge; hunt for the looping teardrop 'peacock-eye' motif on the largest.
The quietest room near the Grand Bazaar — step off the bazaar's edge into the courtyard and the noise drops to fountain water and wingbeats; it is the square's built-in pause.

Things to do

1
Find the three tombs behind the mosque
Slip round the back of the prayer hall into the walled tomb garden. Three mausoleums stand there: Bayezid II's own, his daughter Selçuk Hatun's, and that of Mustafa Reşid Pasha, the grand vizier who launched the Tanzimat reforms in 1839. Three and a half centuries separate the first two graves from the third.
2
Watch the flock lift at dusk
At dusk, stand in the middle of Beyazıt Square facing the mosque. Sooner or later something startles the flock, and hundreds of pigeons lift off the pavement at once, wheeling over the domes in one grey sheet.
