Macau Legislative Assembly Building, Parliament building in Sé, Macau, China

The Macau Legislative Assembly Building is a triangular parliament building in Sé, Macau, completed in 1999 for the handover. Designed by local architect Mario Duarte Duque, it overlooks Nam Van Lake, with the assembly hall at the rear facing the water. It also houses administrative offices, members' offices, an archive and library, an auditorium and a function hall.

Construction of the building began in 1998 and was completed in 1999 for the handover of Macau to China. Before then, the Legislative Assembly met in the historic Leal Senado Building. The new seat was designed by local architect Mario Duarte Duque, who also designed the Superior Court of Macau Building next door.

The building's name appears in Chinese as 澳門立法會大樓 and in Portuguese as Prédio da Assembleia, Macau, and both languages are official in Macau. The Assembly met in the historic Leal Senado Building until the 1999 handover, when it moved into this new home beside Nam Van Lake.

The building stands in the Sé district on the Nam Van Lake waterfront, and its rear assembly hall faces the water. Guided tours are not offered to the general public, so visits are limited to viewing the exterior. The Superior Court of Macau Building, also by architect Mario Duarte Duque, stands next door and can be seen on the same walk.

The architect, Mario Duarte Duque, also designed the Superior Court of Macau Building next door, so the two neighbouring structures share an author. The assembly hall sits at the rear of the triangular plan, looking out over Nam Van Lake. Before 1999 the Assembly met in the historic Leal Senado Building.
