York-Sunbury Historical Museum

York-Sunbury Historical Museum is in the old officers' quarters built between 1839 and 1851, an edifice typical of those designed by royal engineers during the colonial period. The older section has thicker walls of masonry and handhewn timbers. The other, newer end is made of sawn timber.

The museum has a collection from the city's past spread out in 12 rooms: military pieces used by local regiments and by British and German armies from the Boer and both world wars; furniture from a Loyalist sitting room and a Victorian bedroom; aboriginal and Acadian artifacts and archaeological finds. The prize exhibit, though, is a stuffed 19kg frog, the pet of a local innkeeper.
