Town Hall, Colombo, Municipal building in central Colombo, Sri Lanka.

Colombo Town Hall is a neoclassical building 108 m long and 51.3 m wide, its total height equal to its width. The main porch has six Corinthian columns, each 11.6 m tall, with six more on either side of the front and ten on each flank. The council chamber sits on the first floor under a central dome, flanked by open courtyards.

The building came from an international architectural competition in 1922 where S. J. Edwards won against 31 other entries, leading to its opening in 1928. This construction marked a turning point in Colombo's municipal administration and governance structure.

The council chamber on the first floor, under the dome, keeps its original furniture, lamps and lamp bases, and the building's doors and windows are also original. The mayor's official residence is Sirinivasa, the house donated by Dr. W. Arthur Silva in 1925. The elected municipal council meets here.

The main entrance and staircase hall face Viharamahadevi Park, while the two staff entrances sit at the rear corners of the facade. The council chamber is on the first floor, under the central dome, with a public gallery above. The building is an active municipal office, so visitors keep to public areas.

The council chamber and its furniture, including the original lamps and lamp bases, survive untouched by later renovations, as do all the doors and windows and the ornamental lamps on the staircase from the lobby to the second floor. The building's total height equals its width of 51.3 m, and its 108 m length faces Viharamahadevi Park.
