Trienal de Arquitectura de Lisboa

Venue Hire

The Triennale Headquarters, the Palácio Sinel de Cordes, a palace from the 18th Century, has a privileged location with a view over the Tagus river and the National Pantheon. A singular place in Lisbon, our palace can host events like business meetings, conferences, product launches, cocktails, film and photo shoots. Every space on the main floor and garden, each with different dimensions and technical characteristics, can be hired. This is one way we finance the rehabilitation and preservation of the palace, which is well under way.

Besides the list we present here, the palace has other spaces that can be used as support rooms for events, as an example, a fully equipped kitchen; as well as audiovisual equipment and furniture available upon request.
