(highest summit, Hagios Theodoros, 7882 ft.).
In the centre of the plain extends from north-east to south-west a series of low heights, now known as Turcovuni, culminating towards the south in the sharply pointed Lycabettus (1112 ft.), now called Hagios Georgios from the monastery which crowns its summit.
The northern and greater mass culminates in the heights of Anoi (2650 ft.), and the southern in Hagios Stephanos, or Mount Merovigli (2100 ft.).
A ridge of limestone hills - whose principal summits, Hagios Elias and Hagios Simeon, are crowned by old Byzantine churches - runs through the island; for about 2 m.
Originally an island, this headland was in classical times, as now, connected by a narrow bar with the lower promontory of Hagios Nikolaos on the north; it is now united to the mainland also by the sandbar already mentioned.
