Mercersburg Academy
Also known as: Marshall College; Mercersburgh Theological Seminary; Mercersbu

Why it's listed
Mercersburg Academy occupies a large open campus on the east edge of Mercersburg, Franklin County, Pennsylvania. The school was founded in 1836 as Marshall College and the Theological Seminary of the German Reformed Church, and its two surviving original buildings, North Cottage and South Cottage, date from the 1830s. The campus took its present form after 1893, when William Mann Irvine reorganized the institution as a preparatory academy and oversaw construction of nine new buildings. Most are Gothic Revival structures in stone and brick, built within roughly thirty years and forming an unusually cohesive group. The Academy Chapel, completed in 1926 with a 43-bell carillon, is regarded as the most outstanding building on campus. The district is significant for its role in American education and for this architectural collection.
Significance in brief: The district is significant for its association with American education in the 19th and 20th centuries, tracing back to the 1836 founding of Marshall College and the Theological Seminary of the German Reformed Church, and for its architecture. Most central buildings are Gothic Revival, built within a roughly 30-year span, which gives the group unusual stylistic cohesion. The Academy Chapel is regarded as the most outstanding building on campus.

What listing means for this property
This is a historic district. Buildings within its boundary are either contributing (they add to the district's significance) or non-contributing. Owners of contributing income-producing buildings can claim the 20% federal rehabilitation tax credit; homeowners should look at state credits. National Register districts impose no design review by themselves; a local historic district ordinance, if one exists, does (the difference explained).
