Pavilhão Acácio Rosa

The Pavilhão Acácio Rosa sits in the Restelo district of Lisbon. It is a wooden-parquet indoor arena that hosts four different sports for Clube de Futebol "Os Belenenses".

Since opening in 1977 as the Pavilhão do Restelo, the building has served a dual purpose that separates it from standard sports facilities. Its capacity of 1,683 seats is modest, but it has hosted international rock concerts over the years.

The structure has not undergone a major rebuild that would alter its footprint. A redevelopment plan for the wider sports complex was presented in 2016, but the pavilion itself remains its original shape. It is a working space that rarely sees the crowds of a major tournament; it is not a venue for European Cup finals or the EuroBasket championship.

Inside, the wooden floor is described as a floating system, which is standard for the indoor games played there. Basketball and handball are the primary uses, alongside futsal and volleyball. The arena does not host football, which keeps it quietly separate from the city's larger football grounds.

There is no single-record attendance figure that stands out for the arena. The crowd size depends on the sport and the day. It is a functional building that has kept its capacity steady while the city around it has grown.
