The Museu Benfica – Cosme Damião is the museum of Portuguese sports club S.L.

Located near Benfica's stadium, the building occupies 4,000 square metres and is composed of three floors, which are accompanied by a huge vertical parallelepiped made of glass exhibiting roughly 500 trophies won by the club.

The museum is split into 29 thematic areas containing around 1,000 pieces from a collection of 30,000, including trophies, documents, images, audio and video related to the history of Benfica, contextualised into domestic and international historic events of the 20th century.

Moreover, the museum includes audiovisual touchscreens, a hologram of Eusébio, an area displaying photos of Benfica supporters and, lastly, an elevator surrounded by video walls showing messages and images of benfiquistas.

This area transports visitors to a geodesic dome on the top of building, where a short film about the club's history is displayed.
