Church of Saint Catherine, Thessaloniki

About

The Church of Saint Catherine (Greek: Αγία Αικατερίνη) is a late Byzantine-era Greek Orthodox church in the northwestern corner of the Ano Poli, Thessaloniki, in the Central Macedonia region of Greece. In 1988, it was one of fifteen structures inscribed on the UNESCO World Heritage List as the Paleochristian and Byzantine monuments of Thessaloniki.

The church dates to the Palaiologan period, but its exact dating and original dedication are unknown. From its interior decoration, which survives in fragments and is dated to c. 1315, it has been suggested that it was the katholikon of the Monastery of the Almighty. It was converted to a mosque by Yakup Pasha in the reign of the Ottoman sultan Bayezid II (r. 1481–1512) and named after him Yakup Pasha Mosque ( Turkish : Yakup Paşa Camii ).
