Trienal de Arquitectura de Lisboa

open house 2021

September 25 and 26

The Ways of Water by the landscape architecture studio Baldios explores the ancestral paths that connect the cities to the river, settled along the slopes and valleys in Lisbon and Almada. A programme of urban walks, soundwalks and an eclectic selection of spaces is part of this 10th edition (25th and 26th of September).

It was a thrill to receive 12,500 enthusiastic visits, involve 76 passionate specialists, welcome 206 tireless people in volunteer work and, of course, count on the essential generosity of those who opened our doors for us. We're back in 2022.
