It is located at the northwest tip of the island very close to Molyvos. A lush green valley surrounds the village with the awesome long beach. However, its main attraction being its 40-metre high rock on top of which the Church of the Virgin is built.
If you want to go up to the church, you have to climb up 114 carved stone steps. But once you get there, you will be rewarded by an astonishing, breathtaking view. St Nicolas Church is also worth the visit.
The village swarms with old mansions dating back to the 19th and 20th centuries, beautiful gardens etc. The Vareltzidena residence very close to the central square is quite interesting. It is a mansion which has been recently restored and is deemed unique in its kind thanks to its interior design and awesome wall paintings. (Tel: 22530-41510)
