From the 19th century onwards, Praça do Comércio became the seat of some of the most important Portuguese state departaments, including the Ministries of Finances, Internal Affairs, Agriculture and Sea; before the Carnation Revolution (1974) and the creation of a unified Ministry of Defence, it was also the location of the War and Navy Ministries, as well as the old Ministry of Colonies (up to 1967), thus becoming a methonym for the Portuguese central government. Furthermore, the Supreme Court is also housed there.
