General Post Office, Colombo, Historic post office in Fort district, Colombo, Sri Lanka

The General Post Office in Colombo is a postal building in the Fort district with characteristic Edwardian features. The structure displays three architectural column orders: Doric columns in the basement, Ionic elements on the ground level, and Corinthian details in the upper stories.

Construction of the postal building began in 1891 and was completed in 1895. The project was designed by Herbert Frederick Tomalin from the Public Works Department and overseen by local master mason Arasi Marikar Wapchi Marikar.

The building housed Sri Lanka's first public telephone booth, installed on 16 August 1909, and served as the country's first telegraph and telephone exchange after the Ceylon Post and Telecommunications Department bought the Oriental Telephone Company in January 1896. In August 2016 it hosted the fourth Colomboscope arts festival, with installations by Sri Lankan and international artists.

The building is located in the central Fort district of Colombo, where many other historic sites can be found. The location is easily walkable and accessible by public transportation.

The building was constructed on the site of a former rock quarry. This transformation of a raw material extraction site into an important administrative center shows Colombo's urban development.
