The Cortes Gerais (pre-1911 spelling: Cortes Geraes,[1] meaning General Courts in Portuguese) were the parliament of the Kingdom of Portugal during the Constitutional Monarchy period.

[2] The Cortes were established by provision of the Portuguese Constitution of 1822 as a unicameral parliament.

However, the Constitutional Charter of 1826 reformed the Cortes as a bicameral legislature, with the Chamber of Most Worthy Peers of the Kingdom as its upper house and the Chamber of Gentlemen Deputies of the Portuguese Nation as its lower house.

[2] The name of the legislature originates from the traditional Portuguese Cortes, the assemblies of representatives of the three estates, during the period of absolute monarchy.

This building was originally a Benedictine monastery and continues to be until today the seat of the Portuguese parliament, being presently referred as the São Bento Palace.
