The new Coastside History Museum is open! It's located behind the historic 1919 Jail at 505 Johnston St, Half Moon Bay, CA 94019.

The museum is open weekends from 10:30am-4pm.   We are also open during Make it Main Thursday evenings, and some days mid week when docents are available.

The Half Moon Bay History Association has built a new and larger museum that opened on June 24, 2023, with new exhibits and artifacts, on display. 

The historic jail in front of the museum is also open to visitors.

The new museum was built inside the old garage maintaining the historic appearance and most of the structural components of the 1920s sheriff’s garage.
