 The first Christian martyrs used the old quarries of Chrysokava, just east of Kyrenia castle, as catacombs and cut-rock cemeteries which are considered among the island's most important remains from this period.Later, some of these caves were converted into churches and feature beautiful iconography, the most representative of which is that found at Ayia Mavri.From these early days, the town of Kyrenia was an episcopal see.
