Camberley Obelisk (also known as Norris's Obelisk or Norris's Whim) is a brick tower at the top of a hill in Camberley, Surrey, England.
The tower was built by John Norris (1721–1786) in about 1765–1770. The top section of the tower was destroyed by fire in the early 1880s. It is a Grade II listed building.
Although known as an obelisk, the structure is in fact a square tower, made of red bricks. It is built on the top of a wooded hill in Camberley Park, about 200 yards (180 m) east of Camberley town centre.
The tower originally comprised several stories, and is estimated to have been about 100 feet (30 m) in height. However, the top part of the tower was demolished in the late 19th century, and it is now only 30 feet (9.1 m) high. The walls are up to 5 feet (1.5 m) thick.
There was originally a wooden staircase inside the tower, allowing access to the top. The inside of the tower is now empty, and all the entrances have been closed off with iron grids.
