The Round Church, also known as the Old Round Church, is a historic church on Round Church Road in Richmond, Vermont. Built in 1812–1813, it is an extraordinarily rare, well-preserved example of a sixteen-sided meeting house, likely the only remaining example of its kind in North America; the only other known definitively sixteen-sided building in the Northeastern United States is Union College's Nott Memorial. It was built to serve as the meeting place for the town as well as five Protestant congregations. Today, it is maintained by the Richmond Historical Society and is open to the public during the summer and early fall. It is also available for weddings and other events. It was declared a National Historic Landmark in 1996 for the rarity of its form and its exceptional state of preservation.

The Nott Memorial is an elaborate 16-sided stone-masonry building which serves as both architectural and physical centerpiece of Union College in Schenectady, New York. Dedicated to Eliphalet Nott, president of Union for sixty-two years (1804–1866), the 110-foot (34 m) high by 89-foot (27 m) wide structure is a National Historic Landmark, noted for its Victorian architecture.
