The gate and gatekeeper's lodge were built in 1848 and enlarged in 1868-70 with a two-story stone building containing a chapel, offices and tower.","why_significant":"The gatehouse is regarded as an excellent example of Early Gothic Revival design and a rare survivor of its type in Pittsburgh. The 1868-70 addition, with its Second Empire mansard roof and ornate crenellated tower, is described as a fashionable and picturesque composition. The gateway is linked to John Chislett, identified as Pittsburgh's most prominent early architect, who laid out the cemetery grounds.","narrative":"Built in 1848 at the Butler Street entrance of Allegheny Cemetery, the stone gate screen and gatekeeper's lodge follow English medieval models, with a simple Tudor arch, crenellated twin polygonal towers and low relief leaf designs in the spandrels. The cemetery was chartered in 1844, and its first superintendent, John Chislett, designed the gateway and laid out the grounds. In 1868-70 a two-story stone building with a chapel, offices and a tower was added after designs by Henry Moser of Barr & Moser. The addition repeats the Tudor arches and crenels of the original but adds corner pinnacles and a more ornate tower, and a Second Empire mansard roof was placed on the gatehouse. The gateway is valued as an example of nineteenth-century Romantic, picturesque architecture in Pittsburgh, and as one of few surviving Early Gothic Revival structures in the city. The complex remains in use and was recently cleaned.","period_of_significance":"1848, 1868-1870","architect_builder":"John Chislett (architect, gateway 1848); Henry Moser of Barr & Moser (architect, 1868-70 addition)","architectural_style":"Early Gothic Revival; Second Empire mansard addition","criteria":["C"],"status_note":"Unaltered since the 1870 addition, still in use, well maintained, recently cleaned, and in very good condition.","vacant_flag":false,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:30.39447-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/74001734.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/74001734/cccdfe1c1e-800.webp","url_1600":"https://nationalhistoricalregister.com/media/74001734/cccdfe1c1e-1600.webp","licence":"CC BY-SA 2.0","author":"Eli Pousson","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Butler_Street_Gatehouse.jpg\" rel=\"noopener\">Eli Pousson</a>, <a href=\"https://creativecommons.org/licenses/by-sa/2.0\" rel=\"license noopener\">CC BY-SA 2.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Butler_Street_Gatehouse.jpg"},"district":{"nrhp_refnum":"100004020","name":"Lawrenceville Historic District","url":"https://nationalhistoricalregister.com/districts/pennsylvania/lawrenceville-historic-district-100004020/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71997642","wikipedia":"https://en.wikipedia.org/wiki/Butler_Street_Gatehouse","wikidata":"https://www.wikidata.org/wiki/Q5002651"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/allegheny-county/butler-street-gatehouse-74001734/"}
