Calgary Municipal Building, Government building in downtown Calgary, Canada

The Calgary Municipal Building, known as New City Hall, is the seat of Calgary's local government, opened in 1985 beside Old City Hall. It stands on a triangular footprint with a silver mirrored glass curtain wall that steps outward as it rises, above lower walls clad in molded limestone. Its central atrium rises twelve storeys to a rooftop skylight, linked by escalators and glass elevators.

Construction started in 1982 and the building opened in 1985, during a period of fast growth in Calgary. It was built to meet the expanding administrative needs of the city at that time.

The council chambers occupy a large blue cube on the first floor, with councillors seated in a semi-circle facing the public. The room has four entrances and seats 300 people. A raised corridor links the chambers to Old City Hall, letting councillors come and go without crossing the plaza.

The building is open to the public on weekdays. An underground LRT station was built beneath it in the 1980s in case the City Hall CTrain station were moved underground. A raised corridor links the council chambers to Old City Hall.

A time capsule was sealed inside the building when it was completed in 1985 and is not meant to be opened until 2084. It holds objects and documents from that period, making the building a container of the city's own memory.
