This fine mansion was built for the banker Kostaki Teophylaktos in 1889. It's been closed for renovation since 2018 with no news of re-opening.
The Trabzon Museum, also known as Kostaki Mansion, is a historic house museum with archeological and ethnographic exhibitions located in Trabzon, Turkey.
Santa Mariya Kilisesi
This is the only church in Trabzon that still has regular Roman Catholic masses. It was founded by Italian Capuchin monks expelled from Tbilisi in 1845, as part of a long anti-Catholic campaign by the Russian Tsars.
This was rebuilt by the Genoese when they took over in 1306. They called it "beautiful castle", Leonkastron or in Turkish Güzelhisar, which you wouldn't guess from its shambles of a ruin.
This exhibits city history from its Ancient Greek foundation to Ottoman times, plus local natural history and ethnography. Signage is only in Turkish.
Art space and cultural centre in the former city governor's mansion.
St Philip Church
Built as St Philip Church in 1302 and extended into a cathedral in 1461. It was converted into a mosque circa 1665. In 1968 this was rebuilt, so what you see now is retro-Ottoman.
Used as a mosque since 1953, and some believe it used to be St Elefterios Church, built by the Genoese in the 15th century. However it doesn't look it, and more likely that church was closer to the port and long ago demolished. However Hüsnü Köktuğ has a strong claim to be the city's ugliest mosque, with its jarring modern facade. In 2025 it's closed for reconstruction.
