The most alluring part of Hora is the 13th-century residential neighbourhood of Kastro, which Marco Sanudo made the capital of his duchy in 1207. Located behind the waterfront, get lost in its narrow alleyways scrambling up to its spectacular hilltop location.
Several Venetian mansions survive in the centre of Kastro, and you can see the remnants of his castle, the Tower of Sanoudos , which was once surrounded by marble balconies.
Take a stroll around the chapel-dotted Kastro during siesta to experience its hushed, timeless atmosphere. If you lose your bearings (almost inevitable), remember that roads that go up eventually lead to Kastro and roads heading downwards will take you back to the sea.
To see the Bourgos area of the old town, head into the winding backstreets behind the northern end of Paralia.
