La Géode

[1] A refurbishment was announced, and the building closed for works to modernize its concept on 1 December 2018, with plans to reopen to the public in June 2020.

The geodesic dome is 36 metres (118 ft) in diameter, composed of 6,433 polished stainless steel triangles that form the sphere that reflects the sky.

[5] These triangles are 1.5 meters long and are fixed on a thin metal frame with the same triangular geodesic structure, consisting of 2,580 steel tube bars.

[7] Until closing for refurbishment in 2018, movies were projected in IMAX format on a giant hemispherical screen covering 1,000 square metres (11,000 sq ft).

[8] It also presented satellite concert events, including live broadcasts of the Metropolitan Opera from New York City.
