Built inside a ravine, Potamos (potami is the Greek word for river) is the first inhabited village you will come across on the island. Most of the houses of this village are built inside the volcanic rock. Among the most well known churches there are Panagia Giatrissa and Aghios Dimitrios.

Agrilia is the oldest and largest village in Therassia. It has an especially picturesque landscape with houses built into volcanic rock as well as canavas. In the village, you will find the church of Panagia of Eisodia or Panagia of Lagadi which has a unique architecture that dates back to 1887.

The capital of the island is Manolas, which is built on the caldera cliffs and has a magnificent view of Santorini island. The church of Aghios Konstantinos, dating back to 1874, can also be found here.

Kera was an inhabited area about thirty to forty years ago. Today, the area offers many memories of that times as well as a wonderful view. It is well worth getting a complete picture of the island by visiting the monastery Analipseos (the monastery of the Ascension) which can be reached by following the pathway from Manolas.
