Santorini Oia: It lies on the northern side of the island, on top of the cliff. Oia offers a different angle of view on the volcano, the neighbour small islands of Palia and Nea Kameni and Thirassia, a quite impressive one. It is a famous picturesque village and probably the most enchanted place in Santorini.
It is built in the traditional architecture with whitewashed buildings carved into the rock, blue domed churches in narrow streets and sun-bathed verandas. There used to be 79 churches in this small village, but during the earthquake of 1956, many of them destroyed. However the settlement was rebuilt and today attracts many tourists worldwide, who prefer a more calm and peaceful place from Fira and a romantic atmosphere.
You may visit the Maritime Museum, established in 1951, displaying features from the marine life of the area (Tel +30 22860 71156) and the little chapel of St. Nicholas built on the rock.
From Oia there are two paths with steps, one leading to Armeni beach and the other going to Ammoudi beach, where is the small harbour of Oia. From this port small boats may take you to the opposite island of Thirassia. There are a few fish-taverns where one can taste excellent sea food and local wine. Both beaches are only accessible by foot (220-280 steps down)
The highest attraction of the village is the fabulous sunset. A square overlooks the sea and visitors may observe a truly fantastic sunset well worth saving on film.  The most popular spot to watch it is by the Kastro walls. During summer time hundreds of tourists flock to the edge of the village to enjoy the amazing view of sun diving into the open sea.
At Oia you will find plenty of tourist shops, taverns and restaurants, cafes, and some of the most beautiful hotels in the island. There are also enough art galleries for such a small area, as many artists inspired by the beauties of the village and settled here.
