Diamond Rock Schoolhouse, Octagonal schoolhouse in Tredyffrin Township, Pennsylvania, United States.
The Diamond Rock Schoolhouse features eight walls measuring ten feet each, with windows designed to maximize natural light for student learning.
Built in 1818 by Mennonite families of Welsh and German descent, the schoolhouse operated until 1864 when population growth required larger facilities.
The building served as a painting studio for artist Wharton Esherick in the 1920s, who added diamond-shaped shutters and a radial concrete floor.
Visitors can explore the schoolhouse during scheduled Sunday openings throughout summer months or arrange private group tours by appointment.
The educational space accommodated 60 students with benches arranged around a central wood-burning stove, with dedicated walls for each grade level.
