Heritage Museum of Orange County is a cultural and natural history center in Southern California. The centerpiece of the museum, which covers nearly 12 acres in all, is a historic plaza featuring several buildings from the 1890s set amid extensive floral gardens and citrus groves. Among the buildings is the Kellogg House familiar to teachers and students throughout Orange County as a favorite field trip destination for over 30 years.

Additional features found at HMOC include our Gospel Swamp Farm and Gospel Swamp Natural Area. The farm project is maintained by local high school and college volunteers. We’re currently installing a “Borrowing Barn” for tool lending and we utilize produce from the farm for our children’s educational programs and other museum events. Previously on site there was a fully operational blacksmith shop that was headquarters for the Orange County Blacksmith Guild and guild members held regular blacksmith classes. Unfortunately, the shop burned down in the wee hours of July 4, 2019 but through generous donations and grants we were able to rebuild in 2022 and the shop is fully operational now!

The latest major campaign for the museum is to restore the John A. Maag Farmhouse. The home, built in 1899, features three stories in 5,600 square feet of interior living space and is planned for the housing of museum archives, offices and exhibitions. Two original outbuildings of the Maag Farmhouse currently house offices, meeting space and our gift shop.
