ASM Headquarters and Geodesic Dome, Commercial building in Geauga County, United States

The ASM Headquarters and Geodesic Dome is a commercial building in Geauga County, United States. It consists of a low office building and a large open-air geodesic dome made of metal struts and joints.

The complex was built in the late 1950s and dedicated in 1959 as the headquarters for the American Society for Metals. The dome was designed by Thomas C. Howard of Synergetics, Inc., and the surrounding land was later expanded with the purchase of a farm.

The open metal framework has become a local landmark, and people often stop to look up through the struts at the sky. It is a place where the geometry of the dome invites curiosity and a sense of wonder.

The site sits in a campus-like setting with open space around the structures. Visitors can walk around the dome and the main building to see the design from different angles, and the area is easy to explore on foot.

The dome is the largest open-air geodesic dome in the world, and it was never meant to be covered. Its open structure lets visitors see the sky through the frame, which is unusual for this type of design.
