Aula des Cèdres, University auditorium in Lausanne, Switzerland

Aula des Cèdres is a university auditorium in Lausanne, Switzerland. The building has a wide, low form with a gently curving roofline above a broad facade, and its upper section is a continuous band of tall, dark-framed glazing hung with pale vertical strips behind the panes, capped by a thick pale concrete rim; below runs a narrower glazed band, and at the base, centered, is a projecting white vestibule containing four glass double doors flanked by glass panels, with black text reading "AULA DES CEDRES" on a white panel to the right.

Built between 1961 and 1962, the auditorium was designed by architect Jean Tschumi with engineer François Panchaud as part of an expansion of the University of Lausanne. After the EPFL moved to Ecublens, the State of Vaud took over the building, and it has been used by the teacher training college since 2001.

The name comes from the cedar trees in the surrounding park, and the building is now used by the Haute école pédagogique du canton de Vaud for lectures and ceremonies. It also hosts naturalization ceremonies for the canton, so local residents often associate the place with an important personal milestone.

The auditorium sits near the Vaudoise Assurances building in a park with cedar trees, and it is easy to reach by bus from the city center. Visitors should check the program in advance, as the venue is mainly used for academic and official events and may not be open for casual walks inside.

The roof is a thin concrete shell that curves upward at both ends, a bold engineering feat for its time that lets in daylight through tall windows. Inside, a free-standing oval auditorium sits at the center, leaving a passage between the two foyers on either side.
