A museum in
Ault Park near Long Sault is devoted to the Lost Villages, including several historic buildings salvaged from the communities. Other buildings from the villages were moved to the site of
Upper Canada Village in Morrisburg. The flooded area also includes
Crysler's Farm, where a major battle was fought during the
War of 1812. A monument commemorating the battle was also moved from Crysler's Farm to Upper Canada Village. Although
Save Ontario Shipwrecks generally surveys shipwrecks, chapters also explored several of the Lost Villages sites. Guard Lock 21, which was constructed in 1885/86, was flooded in 1936 as headwater for the Hydro dam at
Cornwall. Lock 21 of the former
Cornwall Canal (since replaced by the St. Lawrence Seaway) is a popular
scuba diving site, a few feet from the shore along the Parkway. Mille Roches Power House (1901) at
Cornwall was demolished prior to inundation in 1955 with the new powerdam and seaway nearing completion. In some locations, a few remnants of sidewalks and building foundations can still be seen under the water, or even on the shoreline when water levels are sufficiently low. Some high points of land in the flooded area remained above water as islands, and are connected by the
Long Sault Parkway. ==The Lost Villages==
