Haydar Pasha Mosque, formerly St. Catherine's Church, is a historic mosque in North Nicosia. It is the most important Gothic building in Nicosia after Ayia Sophia, formerly the Frankish cathedral of Nicosia. It has been described by Harry Charles Luke as representing one of the finest examples of Gothic building on the island.
The building was constructed in the 14th century, during the Frankish rule of the island, and named St. Catherine's Church. Upon the conquest of Nicosia by the Ottomans in 1570, it was converted to a mosque.
