Willowbank Estate, Greek Revival mansion in Niagara-on-the-Lake, Canada.

Willowbank is a two-storey Greek Revival mansion built of local Whirlpool Sandstone, with eight hand-carved columns running its full height and a front doorway considered a masterpiece of Greek design. It stands on a lawn hillside above Queenston, reached by an old carriageway that winds up the slope.

Willowbank was built between 1832 and 1834 for Alexander Hamilton, sheriff of the Niagara District and third son of Robert Hamilton, a founder of Upper Canada. Designed by architect John Latshaw in the Greek Revival style, it was constructed of local Whirlpool Sandstone. It is now a National Historic Site of Canada.

The house shows how wealthy families of early European settlers in Canada lived and designed their homes following classical European models. This type of large estate was a sign of power and status in the young colony.

The estate is accessible via Niagara Parkway and now operates as a School of Restoration Arts. Visitors can see the classical architectural elements from outside and explore the grounds that stretch along the river.

The front doorway is described as a masterpiece of Greek design, and the eight hand-carved columns run the full two-storey height of the facade. The house sits on a lawn hillside above Queenston, and the old carriageway winds up the slope so that only glimpses of the building appear before it comes into full view.
