Sanctuary of Poseidon

Remains of the ancient sanctuary are located in the northern part of the island in the centre of the Kalaureian amphictyony. Archeologists estimate it was built around 520 BC. It was here that Demosthenes, the famous orator, poisoned himself with hemlock in 322 BC fleeing from the Macedonian Governor Antipatros.

Holy Monastery of Zoodochos Pigi
Founded in 1720 AD and built on the slope of a pine forest. In 1814, a group of monks from Mount Athos took refuge in this monastery. A few years later, these monks founded the Zoodochos Pigi Monastery at Longovarda on the island of Paros. It is a basilica with a dome and a tower-like belfry being the main church of the monastery. The temple is simple without many wall paintings. The precious wood-carved icon, which was made in Kappadokia of Asia Minor in the 17th century, together with the wood-carved iconostasis and the imposing bishop throne, are of great interest.
