It consists of a long aisle which is roofed by a two slope roof and ends at a sanctuary roofed by two vaults. To the north and south wall of the temple there are windows of different types that were opened either during the Turkish period, or even earlier. To the continuation of the sanctuary and towards the south side of the temple there are chapels. Other building constructions exist to the north and west of the temple.

The finds from this excavation are exhibited in the Historical Museum. The whole area has been expropriated in order to conserve the antiquities and its historical character, as well as to preserve a free view of the venetian monastery. The monastery, partly destroyed during the Turkish occupation, was made into a mosque of Sultan Ibrahim with a minaret at its southwest corner. Today it is reconstructed under the supervision of the 13th Archaeological Service and the Cretan Archdiocese. After the reconstruction, the holy place will be used as a festive temple and a meeting place for international, orthodox, Christian and religious congresses.

At the same site, however, are preserved remains of the Early and Middle Minoan periods (3000-1550 B.C.), mostly cemeteries with well-built ossuaries, and ruins of spacious houses. The site ceased to be inhabited at the same time when Zakros was abandoned (1450 B.C.) but was reoccupied during the Late Minoan III period (1300-1200 B.C.). The city covered a total area of more than 50,000 sq.m., was densely inhabited but not fortified.
