Why you should experience Ontario Museum of History & Art in Ontario, California.
Ontario Museum of History & Art is a civic cultural institution where Inland Empire history and regional art exhibitions unfold inside a preserved 1937 Spanish Colonial Revival building in the city's historic core.
Located on South Euclid Avenue near C Street, just off the tree-lined boulevard that defines Downtown Ontario, the museum occupies the former city hall structure, complete with stucco walls, red-tile roof, and arched entryways that reflect early 20th-century civic design. The interior galleries branch from a central corridor into exhibition rooms calibrated for rotating art shows and permanent local history displays. Large windows filter natural light into lobby spaces, while controlled gallery lighting highlights paintings, photographs, and archival panels. Ontario, California developed as an agricultural and transportation hub long before suburban expansion reshaped the Inland Empire, and Ontario Museum of History & Art anchors that civic lineage in architectural form. The building is part of the exhibit.
What you didn't know about Ontario Museum of History & Art.
Ontario Museum of History & Art presents exhibitions that trace the city's evolution from citrus groves and vineyard estates to rail-centered commerce and postwar suburban growth.
Permanent displays explore the founding of the Chaffey brothers' planned colony, irrigation systems that transformed arid land into farmland, and the development of Route 66 as a commercial artery through the region. Rotating galleries frequently feature regional contemporary artists, emphasizing Inland Empire voices. Archival photographs and early agricultural tools document the area's transformation over more than a century. What many first-time visitors do not immediately register is how locally specific the storytelling remains. Street names, packing houses, and early civic leaders are presented with geographic precision tied directly to surrounding blocks. The museum functions as a concentrated civic memory archive.
How to fold Ontario Museum of History & Art into your trip.
Ontario Museum of History & Art works best as a focused stop within a Downtown Ontario outing.

Inside was a preserved city hall reframed as a layered record of regional development and artistic expression.
