The Blue and Yellow lines (Linha Azul and Linha Amarela) of the Lisbon Metro (Metropolitano de Lisboa) stop at Marquês de Pombal station,[1] which was called Rotunda until March 1998.[2] Eighteen bus lines operated by Carris also serve the square.[3]
In the middle of the roundabout there is a large column dedicated to him, built between 1917 and 1934 and created by Adães Bermudes, António Couto and Francisco Santos. A bronze statue of the Marquess is on the top (40 m), with a lion - symbol of power - by his side. The lower part of the base is surrounded by several allegorical figures, "namely the female figure symbolizing« re-built Lisbon »and three sculptural groups evoking the reforms carried out by the Marquess looking towards the Baixa Pombalina, the area of Lisbon that was rebuilt under his direction after the disastrous 1755 Lisbon earthquake.
