Dallas City Hall and plaza (I.M. Pei)

Dallas City Hall was designed by architect I.M. Pei and completed in 1978; the building is noted for its distinctive inverted pyramid form and granite-clad exterior. The adjacent public plaza acts as an urban installation that has hosted public art, demonstrations, and civic events since the building opened. The building's architectural form and plaza layout were part of a planned civic center development that relocated municipal functions from older downtown sites. The City Hall remains an example of late-20th-century civic architectural installation in Dallas.
