As well as a photographic record of the city, entitled "Memories of Kuala Lumpur", the ground floor has a scale model of Merdeka Square.
The first floor has a viewing deck looking out onto the square, and a scale model of modern KL (still a work in progress as of early 2012).
The building itself has had a varied history; built in 1899, for decades it housed the Government Printing Office of British Malaya. After independence, it was home to first the Ministry of Labour, then the Metropolitan Postal Security Office, before being bought by KL City Hall in 1986. It opened its doors as a public library three years after, a function now carried out by the building next door.
