Bayezid Ağa Mosque

Bayezid Ağa Mosque or Arabacı Bayezid Ağa Mosque is a mosque in Topkapı Square, Topkapı neighborhood, Fatih district of Istanbul. After the conquest in 1453 it was commissioned by Bayezid Ağa, the Sekbanbaşı of Sultan Mehmed II. Over time the mosque fell into ruin and became unusable, and it was rebuilt with the help of the congregation in 1954–57.

In the courtyard’s ablution fountain there is a historic washing basin. In the 1954 construction the walls were made of stone and brick, the ceiling covering of concrete, and the roof covered with tiles. There is a women's section and a muezzin’s balcony. The pulpit and minbar are wooden, the mihrab is plastered. The last congregation area was made as a protrusion.

Bayezid Ağa’s tomb is on the qibla side. Opposite the mosque is the Gazi Ahmed Pasha Mosque complex.
