The walls that completely encompass the Old City date from the Venetian occupation in the 16th century, and have a circumference of three miles (5km). Eleven heart-shaped bastions are interspersed along the walls, which have only three gates, in the north, south and east. One of the gates, the Famagusta Gate, has been restored and serves as the Lefkosia Municipal Cultural Centre, used for exhibitions, conferences, lectures and occasional performances. The gate's vaulted passage leads on to the moat encircling the Old City, which has been planted to create a garden.
