Lisbon Architecture Triennale in Lisbon
The Lisbon Architecture Triennale is a major international exhibition examining contemporary architecture and urbanism, staged across galleries and public spaces in the city roughly every three years since its founding in 2007. Exact dates for the next edition had not yet been announced as of the source check.
Most festivals ask for a weekend or a week of attention; the Lisbon Architecture Triennale asks for patience measured in years.
