It also documents the spread of the Episcopal Church along developing transportation corridors in the mid-nineteenth century, under Bishop De Lancey, local clergy and laymen.","narrative":"Built in 1865 on the corner of West Main and Elm Streets in Port Leyden, St. Mark's Church is a small wooden Episcopal church in the Gothic Revival style. Its board-and-batten walls, tall lancet windows, shallow buttresses and pointed-arch doorways sit on a random coursed stone foundation. Inside, trefoil details decorate the pews, altar rail and altar, and stained glass lights the front gable and chancel. An anonymous local builder adapted the design from plans developed by Richard Upjohn for rural Episcopal parishes. The congregation grew from services held by clergy from nearby parishes, was incorporated in June 1865, and built the church with a gift of land and $500 from Mrs. Augustus Snyder. Port Leyden had prospered as a port on the Black River Canal. The church is valued as an intact example of rural Gothic Revival design in wood and as evidence of Episcopal expansion along transportation routes. It has stayed in continuous service to the village, apart from brief closings.","period_of_significance":"1865","architect_builder":"Anonymous local builder, adapting designs developed by Richard Upjohn","architectural_style":"Mid-19th Century / Gothic Revival","criteria":["A","C"],"status_note":"Still used as a religious facility; the form says the church has remained in continuous service apart from brief closings at unknown dates.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:51:50.541497-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/98001003.pdf"},"photo":null,"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75313351","wikipedia":"https://en.wikipedia.org/wiki/St._Mark%27s_Church_(Port_Leyden,_New_York)","wikidata":"https://www.wikidata.org/wiki/Q7589919"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/lewis-county/st-marks-church-98001003/"}
