Willowbank
An outstanding example of Classical Revival architecture, this stately home was begun in 1833 and completed some two years later. It was erected by Alexander Hamilton (1794-1839), Sheriff of the Niagara District and fourth son of the powerful Upper Canadian businessman, Robert Hamilton, and it possesses a formal elegance befitting the affluence and prominence of the Hamilton family. Constructed of fine quality grey stone, Willowbank is distinguished by four pairs of tall white pillars surmounted by a handsome portico. The classic proportions of the structure are enhanced by its majestic setting in spacious grounds on a rise over-looking the village of Queenston. Owned by the Hamilton family until 1934, Willowbank remains little altered from its original appearance.
