Blackpool Tower is a tourist attraction in Blackpool, Lancashire, England, which was opened to the public on 14 May 1894. When completed Blackpool Tower was the tallest man made structure in the British Empire. Inspired by the Eiffel Tower in Paris, it is 518 feet (158 metres) tall and is the 120th-tallest freestanding tower in the world. Blackpool Tower is also the common name for the Tower Buildings, an entertainment complex in a red-brick three-storey block that comprises the tower, Tower Circus, the Tower Ballroom, and roof gardens, which was designated a Grade I listed building in 1973. The tower celebrated its 125th anniversary in May 2019.
