On Wednesday, July 30, 1958, a provincial plaque was unveiled to commemorate Dundurn Castle on the grounds of the castle in Dundurn Park, Hamilton.
The plaque reads:
DUNDURN CASTLE 1832
This mansion was built 1832-35 by Allan Napier MacNab (1798-1862) and named after the family ancestral seat in Scotland. Enlisting at fifteen, MacNab distinguished himself by his bravery in the War of 1812. He subsequently entered politics and was noted for his support of the Family Compact. During the Rebellion of 1837 he was one of the government's most active military supporters and was knighted for his services. Leader of the Tory-Conservatives, MacNab was Speaker of the Legislative Assembly on several occasions and Prime Minister of Canada 1854-56.
