Los Angeles County spans 4,000 square miles and contains eighty-eight cities plus the unincorporated County government.

Each community has its history, character, and places that help tell its story. Learn more about their preservation efforts, how to get involved at the local level, and featured locations on our map of historic places.

* “Communities” is used to describe the cities and County government since the County isn’t a city. We refer to distinct areas within these communities as “neighborhoods.”
