This elegant residence and its walled garden are a rare and well-preserved example of a country estate in early 19th-century Canada. Built from 1831-1834 for William Thomson, a prosperous farmer, its centrepiece is this finely crafted home in the British classical tradition. The oval entrance drive and the walled garden of nearly half a hectare reflect the original pattern of the grounds. The sheltered environment for growing household vegetables, tender fruit and flowers recalls the walled gardens common in Britain.
