The Glass House, built between 1949 and 1995 by famed architect Philip Johnson, is one of the nation’s greatest modern architectural landmarks. Inspired by Mies van der Rohe's Farnsworth House, the Glass House’s exterior walls are made of glass with no interior walls, a radical departure from houses of the time. The pastoral 49-acre landscape comprises fourteen structures, including the Glass House (1949), and features a permanent collection of renowned 20th century painting and sculpture, along with temporary exhibitions.
