Dundurn Castle is a National Historic Site built in the 1830’s by Sir Alan McNab. Designed in the Picturesque Style, with castle, dovecote, cockpit, coach house, gates and garden set above Hamilton harbour, it is one of the premier historic residential properties in Canada.

Converted to museum use by the City of Hamilton in the early twentieth century, it had become seriously deteriorated by the 1990’s when THA was retained by the City to stabilize, rebuild and restore all the buildings on the site.
