It has historically been the main mosque on the island of Cyprus. The Selimiye Mosque is housed in the largest and oldest surviving Gothic church in Cyprus (interior dimensions: 66 X 21 m) possibly constructed on the site of an earlier Byzantine church.

In total, the mosque has a capacity to hold 2500 worshipers with 1,750 m2 (18,800 sq ft) available for worship. It is the largest surviving historical building in Nicosia, and according to sources, it “may have been the largest church built in the Eastern Mediterranean in the millennium between the rise of Islam and the late Ottoman period”. It was the coronation church of the kings of Cyprus.
