The pond was created in 1730 by George II. It is approximately seven acres (2.8 ha) in extent, measuring approximately 200 by 150 metres (660 by 490 ft). It is up to 5 metres (16 ft) deep. Despite its name, it is not circular, but rectangular with stepped and rounded corners. With a long history of popularity with model yacht enthusiasts, it is the home of the Model Yacht Sailing Association (established 1876) and the London Model Yacht Club (established 1884).
