Burritt on the Mountain is an open-air museum in Huntsville, Alabama. The museum grounds on Round Top Mountain, a plateau connected to Monte Sano Mountain, were the estate of local physician William Burritt, who willed his house and land to the city for use as a museum upon his death in 1955. A number of 19th-century rural structures have been added to Burritt's mansion, both in the interest of historical preservation and life re-enactment.
