The Richwood Academy, historically known as the Mount Pleasant School, is located at 836 Lambs Road in the Richwood section of the township of Harrison in Gloucester County, New Jersey, United States. Built in 1870, the historic schoolhouse was added to the National Register of Historic Places on July 14, 2023, for its significance in architecture and education.[3] The building, also known as the Richwood Academy Cultural Center, is used by the Harrison Township Historical Society for lectures and performances.[4]
The two-story, two-room schoolhouse was built in 1870 by Thomas S. Sharp and James Fletcher. It is the second one located at this site. The first was a one-room schoolhouse built in 1855.[3] The community has been known by various names, Mount Pleasant by 1850, Five Points in 1869, and Richwood in 1889. It was named by "Fancy Joe" Jackson after a relative, Garwood Richwood Marshall.[5] The building was used as a schoolhouse until 1950, when the township elementary school opened. In 1951, the Richwood Academy Association was formed and they purchased the building.[3]
