Avenida da Liberdade extends northwards from Restauradores at a slight incline. It ends at the roundabout named after the Marquis of Pombal, who became Lisbon’s strong man after the 1755 earthquake. He stands at the centre of the swirl of traffic, flanked by a lion, surveying the city centre he created. If you carry on up to the top of Parque Eduardo VII and look to your right, Lisbon’s early 20th-century northern extensions (now very much a part of the “centre”) stretch out before you. Closer at hand is the esteemed Gulbenkian museum; further afield, the 21st-century vistas of Parque das Nações.
