Its hillside siting and windows framing views of the Catskill Mountains are described as a rare local example of the emerging Picturesque Movement. It was also the summer retreat of Rev. Dr. Elbert S. Porter, a Brooklyn pastor and editor.","narrative":"Oakledge is a Greek Revival house built in 1846 on the west side of Route 9H in Claverack, Columbia County. It sits well back from the road on a steep shale ledge planted with oaks, some dating from the time of construction. The two-story frame main block has a pedimented gable, a square-columned porch across the front, and a side-hall entrance with sidelights and a top light. Small single-story wings flank the main block, and because the house is built into the hillside, a finished cellar level opens onto the rear grade. Inside are paired parlors with slate mantels painted to resemble black marble. The rear windows look through an enclosed porch toward the Catskill Mountains, a deliberate framing of the view that reflects the emerging Picturesque Movement. The house is valued as a well-preserved rural Greek Revival design. Rev. Dr. Elbert S. Porter, a Brooklyn pastor and editor, used it as a summer retreat. Three later outbuildings stand behind it.","period_of_significance":"1846","architect_builder":null,"architectural_style":"Mid 19th Century / Greek Revival","criteria":["C"],"status_note":"Still in use as a single-family dwelling; described as retaining a high degree of integrity despite some limited changes, including a modern kitchen.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:51:49.994165-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/97000949.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/97000949/2f0566875c-800.webp","url_1600":"https://nationalhistoricalregister.com/media/97000949/2f0566875c-1600.webp","licence":"CC BY-SA 4.0","author":"Lvklock","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Rev._Dr._Elbert_S._Porter_House.jpg\" rel=\"noopener\">Lvklock</a>, <a href=\"https://creativecommons.org/licenses/by-sa/4.0\" rel=\"license noopener\">CC BY-SA 4.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Rev._Dr._Elbert_S._Porter_House.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75312401","wikipedia":"https://en.wikipedia.org/wiki/Rev._Dr._Elbert_S._Porter_House","wikidata":"https://www.wikidata.org/wiki/Q7317673"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/columbia-county/porter-rev-dr-elbert-s-house-97000949/"}
