The DNA Tower is closed for maintenance until late May 2021.
The DNA Tower derives its name from the deoxyribonucleic acid (DNA) double-helix molecule, which is found in all cells and control the development of life.
Dr John Beard (Director of Kings Park and Botanic Garden 1961-1970) commissioned the construction in 1966 by D&H Fraser Consulting Engineers. The 15m high staircase has 101 steps and was inspired by the famous double staircase in a Chateau in Blois, France.
The paving and wall surrounding the DNA Tower was constructed using stones from 11 towns and 80 shires within Western Australia. The original design included a shallow reflecting pond at the base of the tower. It was replaced with Karratha stone paving in 2001 to enhance visitor safety.
The DNA Tower is located at the Forrest Drive end of the Broadwalk Vista. It is an easy 1.5 km walk from May Drive Parkland and the Western Australian Botanic Garden.
