The museum was established and is still run by, the Wiltshire Archaeological and Natural History Society (WANHS), a registered charity founded in 1853. After the purchase of an old grammar school the museum was opened in 1873. Subsequently it expanded into two Georgian houses on either side and still occupies this location today.
