The most impressive part of Hora is the Castle (Kastro), which is built on the edge of the sheer cliff that reaches 200 metres.It is a very well-preserved and well-established medieval settlement, like all of this type, to protect the property of the people of the island from the raids of the pirates.The area of the Kastro, a small fortress made by the Venetians in 1210, a small village into the Hora village, will take you back to the Middle Ages. The northern side of the castle is built on the eyebrow of a steep cliff over 200m. Inside the castle there are many old churches with interesting architectural features. The most important are Pantanassa, Eleousa, and Agia Anna.Most homes have been inhabited for at least ten centuries and the island’s inhabitants keep it in good condition.Access to the castle is only on foot because the vehicles are forbidden because the two entrances, Lodzia and Paraporti, have stairs.
The village of Kastro was lived in continuously throughout the centuries and there are still today many houses and alleyways that maintain a special, traditional character.
