Every year IMUN is held at the Centro Cultural de Belem  in Lisbon.  Located by the Rio Tejo, the CCB is a state of the art conference center.  The rooms are equipped with a state-of-the-art sound system and are extremely spacious and comfortable.

CCB is located adjacent to a train station which serves Cascais and Estoril a mere 30 minute train ride alongside the ocean.
