Wisteria Hall, located adjacent to the Washington Park Arboretum Visitors Center, is one of two event sites run by the UW Botanic Gardens. (The other site is the Center for Urban Horticulture, a little over two miles North.) Indoor Wisteria Hall rents with two beautiful outdoor terraces in the heart of the 230-acre park . Weddings, receptions and corporate holiday parties are just a few of the social events that take place in Wisteria Hall. In addition this is the perfect place for a business meeting or retreat – without having to travel out of city!
