The Lisbon Architecture Triennale is a non-profit association whose mission is to research, foster and promote architectural thinking and practice. It holds a major forum every three years for the debate, discussion and dissemination of architecture across geographic and disciplinary boundaries. The first Triennale, "Urban Voids" took place in 2007 with a programme of international exhibitions, competitions and conferences drawing 52,000 visitors and participants. In 2010, its second edition "Let’s Talk About Houses" consolidated the Triennale’s presence in the circuit of events devoted to architecture with an estimated 154,000 attendees. Now, from its new headquarters in the Sinel de Cordes Palace, where a creative cluster is being established, the Triennale organizes as well "Intervalo", a programme which happens between each edition of the Triennale event.
The Lisbon Architecture Triennale was distinguished in its three editions (2007,  2010 and 2013) with the High Patronage of His Excellency the President of the Portuguese Republic and since 2010, it was also awarded the status of Cultural Interest by the Ministry of Culture.
