Oia or Ia is a small town in the South Aegean on the island of Santorini. Oia was previously known as Apano Meria and the inhabitants are still called Apanomerites. At the pinnacle point of Oia is the ruined castle which was the seat of the Argyri family under the Venetians and serves as a lookout point with a complete 360-degree view. There are many kiosks offering a range of ethnic goods, handicrafts, jewellery and souvenirs, and several small art galleries, including Art Gallery Oia and The Art Gallery. The town also has numerous restored churches, including Panagia church; some were built in memory of sailors.

Fira is the modern capital of the South Aegean island Santorini. Fira derives its name from the original name of the island itself; Thira. Fira is a city of white-washed houses built on the edge of the 400 metres (1,312 feet) high caldera on the western edge of the semi-circular island of Thera. The two main museums of interest are the Archaeological Museum of Thera, 30 metres (98 feet) east of the cable car entrance, and the Museum of Prehistoric Thera at the southeast corner of the White Orthodox Cathedral of Ypapanti, built on the site of an earlier church destroyed in the 1956 earthquake.

Kamari is a coastal village on the southeastern part of the Aegean island of Santorini, Greece. The village got its name from a small arch that still rises at the south end of its beach and is what remains from an ancient sanctuary dedicated to Poseidon. Today, it stretches along a beach covered with black pebbles, which is the longest of the island. The beach extends in a northeast to southwest direction from Monolithos to the feet of the Mesa vouno mountain that rises up to a height of approx. 400m, being Santorini's second highest peak. Once an agricultural and fishing village, modern Kamari boasts a thriving tourist industry, offering a wide choice of accommodation, restaurants, cafes, bars and night clubs, plus several water sport activities.
