The Marquis of Pombal Square (Portuguese: Praça do Marquês de Pombal) is an important roundabout in the city of Lisbon. It is located between the Avenida da Liberdade (Liberty Avenue) and the Eduardo VII Park.
Its name is a reference to Sebastião José de Carvalho e Melo, Marquis of Pombal, the mighty prime-minister who ruled Portugal from 1750 to 1777. In the middle of the roundabout there is a large column dedicated to him, built between 1917 and 1934. A bronze statue of the Marquis is on the top, with a lion - symbol of power - by his side. The Marquis is shown looking towards the Baixa Pombalina, the area of Lisbon that was rebuilt under his direction after the disastrous 1755 Lisbon Earthquake.
The Blue and Yellow lines (Linha Azul and Linha Amarela) of the Lisbon Metro stop at Marquês de Pombal station. Eighteen bus lines operated by Carris also serve the square.
