Half Moon Bay Coastside History Museum is Now Underway!

The Half Moon Bay History Association has opened a mini-museum highlighting Coastside history in the historic jail in downtown Half Moon Bay. The jail museum is staffed by trained docents and is open weekends from 10 a.m. to 4 p.m. Weekday group tours can be arranged by contacting HMBHAdocents@gmail.com.

A project to convert the Johnston Barn, located just behind the jail building, to a larger museum space is underway. Donate now to support our efforts to celebrate Coastside legacies through these museums and our other programs.

Our docent training program equips volunteers to interpret the many turning points that have made the Coastside what it is today:

  • the native Ohlone who inhabited villages in each watershed for 12,000 years
  • the Gaspar de Portolá Expedition who mapped the area for Spain in 1769
  • the Spanish colonists who followed Juan Bautista de Anza, dotting the coast with missions and presidios
  • Mexican land grants and secularization that released mission lands for agriculture
  • the Gold Rush
  • whaling and other maritime activities
  • the Ocean Shore Railroad
  • Prohibition
  • World War II
  • the rise of Silicon Valley and the Information Age

We’re continually seeking volunteer donors. To learn more, contact HMBHAdocents@gmail.com.
