610 York Blvd. is the location of one of Hamilton's most-recognized landmarks. Dundurn Castle is a National Historic site that illustrates the life and times of Sir Allan Napier MacNab (1798 - 1862), lawyer, landowner, railway magnate and Premier of the United Canadas from1845 to 1856.

Sir Allan MacNab left his mark on the growing town of Hamilton by helping to establish the railway, the first bank and representing the area for thirty years in Parliament. MacNab was an important figure in the pre-Confederation history of Canada. He was declared a "Boy Hero" for his role in the War of 1812. Following his support of the royalist cause in the Upper Canada Rebellion of 1837, Queen Victoria knighted MacNab. This house was completed in 1835 after three years.

Designed as a fashionable Regency style villa, Dundurn (Gaelic for "fort on the water") was nicknamed "Castle" by the citizens of Hamilton. The Castle, with its gardens, grounds and many unusual outbuildings, was one of the finest estates in the province.

When you visit, you’ll see the house contains forty furnished rooms, above and below stairs, that will enable you to compare the life of a prominent Victorian family with that of their servants. You’ll learn about daily life in the 1850s from costumed staff who will guide you through the home.

Located within the Dundurn grounds is the Hamilton Military Museum. Be sure to spend some time here where you’ll see displays of Candian uniforms and equipment. Weapons from 1800 are also on display. There is an admission charge to the castle and the museum.
