Per the Maryland Department of Planning: The mansion along Butterfly Lane in Frederick, was one of 16 projects around the state to receive a portion of the $19 million in rehabilitation tax credits awarded to revitalize Historic buildings.

Prospect Hall is a large, elegant hilltop two and a half story Greek Revival mansion with a seven-bay brick central block and added dependencies on each end. Extending from the front of the house is an imposing two and a half story pedimented portico supported by concrete-coated, round, brick columns with Roman Ionic capitals. Built during the early 19th century with subsequent additions and alterations, the mansion is atypical for its period and location due to its grand proportions and design. While minorly altered for its use as a school in the 1950’s, the original central portion retains a high degree of its formal historic layouts, features, and finishes, retaining its grand central hall with four adjacent rooms, including two formal parlors, a dining room, and decorative stair hall intact. The core rooms of the second floor remain intact and are oriented around a long central hallway, with two arched openings leading from the decorative stair hall to the central hall. The attic, finished in the late 19th century, still retains its historic partitions and finishes.

The project will involve an exterior and interior rehabilitation with associated site improvements to transform the property into an event venue, according to the press release. Estimated Total Cost – $3 Million

The Prospect Hall mansion was built in the early 1800’s and was home to St. John’s Catholic Prep before moving to their current location in Buckeystown in 2013.
