Quartel do Carmo
The Convent of Carmo was founded in 1389 by the military commander and saint D. Nuno Álvares Pereira. The great earthquake of 1755 and the subsequent fire left in ruins much of the convent and its church. In 1836, the inhabitable part of the convent was converted into military barracks.
During the Carnation Revolution of 1974, it was in the Quartel do Carmo, the General Command of the Republican National Guard, that the prime minister of the "Estado Novo" government, Marcelo Caetano, sought refuge from the military revolt. The siege of the Quartel do Carmo was led by captain Salgueiro Maia.
