Chertsey Museum is the local authority museum for the Borough of Runnymede and is funded by Runnymede Borough Council with support from the Olive Matthews Collection Trust.
The museum is staffed by a full time Curator, full time Education Officer, part time Keeper of Costume and six part time Museum Assistants, and is supported by volunteers and The Friends of Chertsey Museum.
Chertsey Museum first opened in 1965 in the Old Town Hall, Chertsey. At this time it was run by volunteers and was run by Chertsey Urban District Council. In the early 1970s two significant events happened. Firstly, CUDC went in to partnership with the Olive Matthews Trust and the museum moved to its current home,The Cedars, and secondly the two District Councils of Chertsey and Egham merged to form the Borough of Runnymede. From this point onwards, Chertsey Museum became the local museum for the whole borough.
In 2003 Chertsey Museum expanded with an extension to The Cedars; this education space has enabled the museum to continue to grow and meet the needs of the local community.
