The museum comprises 15 structures: the Main Adobe, a Fountain, a Chapel, a Bell Structure, and a Winery, all built in the 19th century. Structures built in the early 20th century include a Barn, Gas Station and Bunkhouse, The Small Adobe, and a Schoolhouse. All of these structures help visitors to get a sense of what life was like for earlier inhabitants of the area. Rancho Camulos is also known as the "Home of Ramona." Helen Hunt Jackson's 1884 best-selling novel Ramona inspired four motion pictures and a pageant performed annually in Hemet, California.
