Angra do Heroísmo, locally referred to as Angra, is a municipality and city (of approximately 21,300 people) on the island of Terceira, within the Portuguese autonomous region of the Azores. The population in 2011 was 35,402, in an area of 239.00 km². Along with Praia da Vitória to the north, it is one of two municipal administrative divisions that are comprised by Terceira. Together with Ponta Delgada (São Miguel) and Horta (Faial), Angra is one of the three regional capitals of the Azores. Each capital is responsible for one of the three branches of government; Angra is the location of the judicial branch (the Supreme Court of the Azores), in addition to being the religious centre of the Archdiocese of Azores.
Dating back to 1450, classified as a World Heritage site by UNESCO in 1983. Some claim that Angra was founded by Álvaro Martins, who sailed with Didrik Pining on his expedition to the New World, and with Bartolomeu Dias on his voyage around the Cape of Good Hope. Others contend that Angra was founded in 1450 or 1451 by Jácome de Bruges, a Fleming in the service of Prince Henry the Navigator, who recruited farmers, fishermen, and merchants in the Low Countries to colonize the Azores.
Angra served as a place of exile for Almeida Garrett during the Napoleonic Wars. It also served as a refuge for Queen Maria II of Portugal from 1830 to 1833.
The word Heroísmo («heroism») was added to the name of the city, Angra (meaning «inlet» or «cove»), by Maria II, in recognition of the bravery and sacrifice shown by the people of Angra in the struggle that ended with the formation of a liberal constitutional monarchy in Portugal.
