The Topanga Historical Society (THS) was organized in 1974 by a group of dedicated community leaders who recognized the urgent need to collect and preserve records of Topanga’s unique history and to make them available to future generations. The Society maintains an Archive Center and presents quarterly local history programs.

The Homestead Museum collection includes a diverse array of items from Los Angeles and the Los Angeles Region covering the general period of 1830 to 1930 and includes ephemera, maps, photographs, printed works, and three-dimensional everyday artifacts. The Homestead Museum is a participant in the LAAS and ONE Archives Hidden Histories project.
