It was constructed between 1825 and 1832 by the "Children of Peace", a sect led by former Quaker David Willson on whose property it was built. Other restored buildings include David Willson's Study, which is a smaller architectural gem. The Ebenezer Doan house of 1819, constructed by the temple's master-builder and relocated from the former Doan family farm nearby, has been restored in an early garden setting. Also on site are the "cook house" where communal meals were created and served, the "drive shed' complete with period carriages, and another of David Willson's architectural curiosities – the round outhouse. The Ontario Heritage Trust has a public easement to ensure its preservation meets conservation standards.
