Lapau, Royal ceremonial hall in Pusat Bandar, Brunei.

The Lapau is a ceremonial hall in Bandar Seri Begawan with a golden domed ceiling, facing the Royal Regalia Museum and the Brunei History Centre. It stands next to the Dewan Majlis, the former Legislative Council building. Entry requires official permission.

The hall was completed in 1968 as a replacement for an earlier structure on the site. It later served as the location for the coronation of Sultan Hassanal Bolkiah as the 29th Sultan of Brunei.

The hall hosts ceremonies like the Gendang Jaga-Jaga ensemble performances and Naubat traditions, which mark royal celebrations and periods of mourning for the sultanate. These events shape how people understand the connection between the monarchy and national identity.

The venue is dedicated to state ceremonial events and official functions, so access is restricted to certain times. It is advisable to check in advance whether the hall is open to visitors, as it may be reserved for royal functions.

The building's plan was first proposed in 1963 by Sultan Omar Ali Saifuddien III, and the design was later refined by the firm Booty Edwards & Partners. Construction ran from August 1965 to 1968 on a site then in Kampong Kianggeh. On 23 November 1971 the agreement granting Brunei full internal independence, except defence and foreign affairs, was signed here.
