It is a square two-story structure with a seven-sided two-story tower at the southeast corner.","why_significant":"The nomination argues that it is the first toll house within Pennsylvania on the road from Cumberland and the only extant stone toll house of its design on the Pike. Its design and relation to the National Road's history, including toll collection until 1905, are the basis for its significance.","narrative":"Built around 1835 as one of six toll houses along Pennsylvania's section of the National Road, this square stone structure has a hipped roof, a seven-sided two-story tower on its southeast corner, and a brick chimney at its northern end. The toll window and main door are set in the tower. A small wooden kitchen was added to the west around 1888, and a porch supported by square posts shades the tower's first story. The interior holds a sitting room with a fireplace, a kitchen, a parlor with a fireplace, and a second-story bedroom. The road was authorized by the federal government in 1806 and was later handed to Pennsylvania to administer. Tolls were collected here until 1905. The house is regarded as the first toll house in Pennsylvania on the road from Cumberland and the only surviving stone toll house of its design on the Pike, which gives it its importance to the road's history.","period_of_significance":null,"architect_builder":null,"architectural_style":null,"criteria":[],"status_note":null,"vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:29.995316-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/79002346.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/79002346/cb764315fc-800.webp","url_1600":"https://nationalhistoricalregister.com/media/79002346/cb764315fc-1600.webp","licence":"Public domain","author":"A.S.
