The Dome is a historical building, initially constructed in 1837 to protect the main source of water supply for residents in the 18 century. The upper section was inhabited by the dome keeper. In 1893 the development of piped water was introduced to homes and hence the dome became a secondary source of water in times of drought. In 2005, Doctor’s Cave Bathing Club donated the funds needed to ensure that the historical structure of the building was rehabilitated.
