The Butterfly House is located within Williamson Park in Lancaster, housed inside an Edwardian palm house structure. It functions as a tropical conservatory featuring free-flying butterflies amidst exotic plants. The enclosure maintains a warm, humid environment to support butterfly life cycles and vegetation. Visitors can observe various species at different stages of development, including pupae in the emergence cabinet. It is situated adjacent to the park's mini-zoo facilities, which include habitats for meerkats, marmosets, and bird species. The site is part of a larger 54-acre parkland development that features the Ashton Memorial. The conservatory glasshouse provides a managed ecosystem that functions independently of the external Lancashire weather.
