The Glass House, built between 1949 and 1995 by architect Philip Johnson, is a site of the National Trust for Historic Preservation located in New Canaan, CT. The pastoral 49-acre landscape comprises fourteen structures, including the Glass House (1949), and features a permanent collection of 20th-century paintings and sculptures, along with temporary exhibitions. The campus serves as a catalyst for the preservation and interpretation of modern architecture, landscape, and art; and a canvas for inspiration and experimentation. The tour season runs from April 15 to December 15 and reservations are required.
