The Christopher Erb House is a stone house finished in 1799. It is a well-preserved example of a Pennsylvania German stone structure, and reflects the influence of Pennsylvania Germans in Carroll County.
It was listed on the National Register of Historic Places in 1985.
The main house features a date stone in the western gable, and was constructed as a two-family German style house. However, the exterior is in the Georgian style. The property also features a two-story spring house, probably the first structure. It is a traditional German colonial house, with a spring room and kitchen room on the bottom level. This house is listed in the 1760 tax records, and is assumed to be constructed between 1755 and 1760.
