Owned and operated by the state of New York, Fort Ontario is an important historic site that was named for its location overlooking Lake Ontario. The original fort was built in 1755, but the building that stands today was constructed in the 1840s and upgraded during the 1860s and early 1870s.

Several structures are open to the public, including two officers' quarters, the storehouse, the powder magazine, and the men's barracks. Guided tours are available, but visitors are also welcome to explore the fort on their own and to enjoy the beautiful picnic areas on the grounds.
