Inspired by their World War I experience in Belgium, Mabel Cawthra and Agar Adamson commissioned this Flemish gabled mansion. The land was acquired in 1805 and the family built a small cottage for summer vacations. The gatehouse was built in 1904 for guests. The new house was built in 1920. This parcel is what remains of the original 300 acre summer property on Lake Ontario. It contains a two-storey manor house, in the Colonial Revival and Flemish style, a wooden gatehouse or folly, a barn, and a pet cemetery. The grounds are now a public park on the Waterfront Trail.
