Château de Vullierens is primarily distinguished by its extensive collection of over 400 varieties of irises, which bloom across 100 hectares of parkland. The estate features a historic 18th-century castle built on the site of a 13th-century fortress, overlooking Lake Geneva and the Alps. Beyond the iris gardens, the site hosts permanent contemporary art exhibitions, including massive sculptures installed throughout the grounds. The gardens are designed with a focus on historical botanical variety, including a lily garden and a tulip collection. The site functions as both a private residence for the family owners and a public botanical and cultural center. It is located in the Vaud region of Switzerland, roughly midway between Lausanne and Geneva.
