The Baixa, also known as the Baixa Pombalina is a neighborhood in the historic center of Lisbon, Portugal. It consists of the grid of streets north of the Praça do Comércio, roughly between the Cais do Sodré and the Alfama district beneath the Lisbon Castle, and extends northwards towards the Rossio and Figueira squares and the Avenida da Liberdade, a tree-lined boulevard noted for its tailoring shops and cafes.
