Pleasant Grove School
Also known as: Mud College
Why it's listed
Built in 1869 beside the Baltimore Pike in Mount Joy Township, Adams County, this one-story, gable-front brick schoolhouse measures about 26 by 32 feet and sits on a rubble stone foundation. Locally nicknamed "Mud College," it served the township's children in grades 1-8 until it closed in 1949. The interior keeps its oak floor, raised teacher's platform, slate blackboard, pot-bellied stove and four rows of ten original wooden desks. A replica belfry was installed in 2001 after the original blew off in a storm. In 1951 a local family bought the building to preserve it, held annual reunions there, and gave it to the township in 2000. It now operates as a living history museum with a program for area students. The school was listed for its role in local education, with a significance period of 1869 to 1962. It is described as the only municipally run original one-room school museum in Adams County.
Significance in brief: The nomination argues the school meets Criterion A in the area of Education. It provided continuous public education in grades 1-8 to hundreds of local children from 1869 to 1949. After closing it was bought by a local family, preserved, and given to the township in 2000. It is described as the only municipally owned and operated original one-room schoolhouse museum in Adams County.

What listing means for this property
For a publicly owned building or structure, listing mainly matters when federal funds, permits or licences are involved: projects then go through Section 106 review so effects on the property are considered. Listing also strengthens applications for preservation grants and, for leased income-producing uses, can enable the federal rehabilitation tax credit.
