The buildings date from about 1880 to 1920.","why_significant":"The district has been the focus of East Liverpool's central business district since the late 19th century. It is also a cohesive collection of well-preserved late 19th and early 20th century commercial buildings from the city's most prosperous growth period. The Thompson Block and the Little Building are singled out as visual landmarks.","narrative":"Eight commercial buildings cluster around The Diamond, an open space formed where Market and Sixth Streets meet in downtown East Liverpool, Ohio. Built between about 1880 and 1920, they range from two-story brick Victorian blocks to the five-story Little Building, finished in buff brick and glazed terra cotta. The Thompson Block, with its corner turret, colored glass transoms and central gable, is cited as one of the finest examples of late 19th century eclecticism. The district grew up as the pottery industry drove the city's population from 5,500 in 1880 to over 22,000 in 1905, and commerce moved up from the riverfront to this spot. The Diamond has hosted a monument, parades, public gatherings and War Bond sales, and is now a landscaped park. The buildings share brick and terra cotta materials and a scale of two to five stories, forming a visually cohesive unit that records East Liverpool's most prosperous period.","period_of_significance":"1880-1920","architect_builder":null,"architectural_style":"High Victorian Commercial, Queen Anne, Italianate, neo-classical influence and Art Deco storefront, plus restrained early 20th century commercial styles","criteria":[],"status_note":"Most buildings are in commercial use; the form reports exteriors in fair to excellent condition, and some storefronts have been altered.","vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:53:14.343243-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_OH/85003508.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/85003508/c152a7eed6-800.webp","url_1600":"https://nationalhistoricalregister.com/media/85003508/c152a7eed6-1600.webp","licence":"Public domain","author":"Nyttend","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Diamond_Historic_District,_East_Liverpool.jpg\" rel=\"noopener\">Nyttend</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Diamond_Historic_District,_East_Liverpool.jpg"},"district":{"nrhp_refnum":"01000591","name":"East Liverpool Downtown Historic District","url":"https://nationalhistoricalregister.com/districts/ohio/east-liverpool-downtown-historic-district-01000591/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71984552","wikipedia":"https://en.wikipedia.org/wiki/Diamond_Historic_District_(East_Liverpool,_Ohio)","wikidata":"https://www.wikidata.org/wiki/Q5270828"},"indexable":true,"url":"https://nationalhistoricalregister.com/ohio/columbiana-county/diamond-historic-district-85003508/"}
