Almeida is a Portuguese raiana village belonging to the Guarda district in the province of Beira Alta, Central region (Beiras Region) and sub-region of Beiras and Serra da Estrela, with about 1,300 inhabitants.
It is the seat of a municipality with 517.98 km² in area and 7 242 inhabitants (2011), subdivided into 16 parishes. The municipality is bordered to the north by the municipality of Figueira de Castelo Rodrigo, to the east by Spain, to the south by Sabugal and to the west by Guarda and Pinhel. The present municipality results from the junction, in the nineteenth century, of three secular municipalities: Almeida, Castelo Bom and Castelo Mendo, whose former headquarters are three fortified medieval villages, which are today poles of tourist interest.
The town of Almeida is known for its fortress, which, with its twelve-pointed star shape, is one of the most spectacular European examples of 17th century bastioned defensive systems. Almeida Fort Square is a candidate for the UNESCO World Heritage category.
