Corvo Island is the smallest of the Azores Islands, being just 17.45km2 (6.75 sq mi) in area and having only 400 inhabitants and only one municipality, Corvo.
The highest point in Corvo is Mont Grosso, at 770m (2530 ft). The island was formed by the collapse of a volcano to form a caldera. Known on the island as "Caldeirão," the caldera is 300 m (980 ft) deep and has a perimeter of 3.7 km (2.3 mi).
The island was discovered in 1452 by Diogo Teive.
