In the second half of 2007, the baton of the EU Council Presidency was passed to Portugal. The country decided to hold the majority of the planned meetings, conferences and summits centralised at a location in Lisbon. The chosen venue was the Sala Tejo of the Pavilhao Atlantico, which was converted to host the meetings on the future of Europe, culminating in the Treaty of Lisbon. The architects commissioned for this project, Baixa, Atelier de Arquitectura, successfully gave the venue - as well as the event - an impressive identity, marked by Portuguese culture and contemporary architecture. This book pays tribute to this ephemeral piece of architecture with a comprehensive collection of sketches, drawings and photos. In the accompanying and introductory texts, the project is viewed through the eyes of two well-known architecture critics as well as the Head of Mission of the Portuguese Presidency.
