City of Ontario

The Ontario Museum of History & Art, part of the City of Ontario’s Museum, Arts & Culture Department, preserves, interprets, and celebrates the history and cultural heritage of Ontario and the surrounding area. The department also produces annual events that highlight the experiences and traditions of Ontario’s diverse community, connecting residents and visitors with local stories through exhibitions, programs, and festivals.

Its exhibitions explore subjects significant to the region. Built on Water: Ontario and Inland Southern California examines the history and future of water in Ontario and the Chino Basin, bringing together local water agencies, regional tribes, agriculture, conservation, and the city’s development. Visitors can encounter historical artifacts and images, community voices, a mobile app about water management, and a virtual reality experience featuring a monarch butterfly. Moments That Made US considers how generations of Americans have interpreted the ideals of the Declaration of Independence. The department also presents the Ontario Arts Festival and hands-on Studio Saturdays programs, while sharing updates about exhibitions and events through its email newsletter and social media.
