Willowbank is an independent educational institution located on the Willowbank National Historic Site and in the village centre of Queenston, Ontario, along the Canada-United States border. It operates a School of Restoration Arts which offers a three-year post-secondary diploma in conservation skills and theory, and a Centre for Cultural Landscape, a forum for cultural landscape theory and practice in Canada and the world. Willowbank was created from the rescue of a 19th-century estate which today forms the centre of its campus, and it is one of a handful of Canadian organisations of which His Royal Highness The Prince of Wales is Royal Patron.
