İçkale Mosque

Large walk-through aquarium.

Built in the 13th century as a church dedicated to Saint Eugenius, the patron saint of the city. Eugenius was a martyr under the persecutions of Diocletian around 305 AD. His holy intercession supposedly saved the city from Turkish assault in 1224, but did nothing to halt the conquest by Mehmet in 1461. The church was thereafter converted to a mosque, which remains in use and is only open for prayer times.

Founded in 1514 by Selim, then governor and later Sultan, in honour of his mother. Gulbahar Hatun (1453-1505) was originally a slave girl and became the concubine of Bayezid II; her tomb is here. The mosque was repaired in 1883.

The "Golden domed church of All Saints" was built in the 10th or 11th century on much earlier foundations - until the 4th century AD it was the scene of Mithras worship.In the Middle ages it was the city cathedral, and hosted coronations for the Emperors of Trebizond. It was converted to a mosque when the Ottomans took over in 1461. Restoration in 2017/18 uncovered more original features, and a raised glass platform enables you to see the fine late-Roman mosaic floor.

Restored mansion with photographs, documents and artefacts describing the city in the Ottoman and Republican periods. Signage is only in Turkish.

Sturdy Ottoman mosque built in 1822.
