{"id":647,"slug":"oswego-market-house-new-york","story":[{"heading":null,"paragraphs":["Oswego's Market House was where abolition nominated a president. The Federal-style building went up in 1835-36 on the Market Ground — village offices upstairs, a post office, a jail, market stalls below, Jacob Bonesteel building it on the model of Philip Hooker's Washington Market in Albany. When Oswego incorporated as a city in 1848 it became the first City Hall. And in 1850 it hosted the National Liberty Party convention — the abolitionist party nominating Gerrit Smith for president and, for vice president, Samuel Ringgold Ward: a man born enslaved in Maryland, standing for national office on American soil a decade before the Civil War.","Ward's nomination is the detail that marks the building — an abolitionist party putting a formerly enslaved man on a presidential ticket in a lake city that was the Underground Railroad's last American port, where the Black barbers and sailors of Oswego ran the boats to Kingston. The Market House sat at the center of that city — the municipal building where commerce, courts, jail, and the antislavery politics that defied the Fugitive Slave Act all operated under one roof.","The building outlived its city-hall role — sold to the railroad in 1864, used for commerce and entertainment for another century and a half, and still standing on Water Street, the Federal facade facing the river where the boats left for Canada.","The Market House is the archive's nomination file — Oswego's first city hall, where the Liberty Party put a formerly enslaved man on a presidential ticket in 1850, in the lake port that was the last American stop before Canada."]},{"heading":"Why this file matters","paragraphs":["The Oswego Market House is the archive's ticket file — the 1835 municipal building where the National Liberty Party nominated Gerrit Smith and the formerly enslaved Samuel Ringgold Ward in 1850, in the port city where the Underground Railroad's last boats left for Kingston.","A market that nominated the formerly enslaved keeps its hall — the file's suggestion being that the Market House's hold is 1850: the convention that put a man born enslaved on a presidential ticket, in the city where his people shipped for Canada."]}],"name":"Oswego Market House","aliases":[],"type":"HISTORIC_SITE","type_label":"Historic Site","cats":["DARK_HISTORY","UNDERGROUND_RAILROAD_HISTORY","AFRICAN_AMERICAN_HISTORY","HISTORIC_SITE","UNDERGROUND_RAILROAD","COMMERCIAL"],"groups":["dark-history","historic-sites"],"desc":"NPS-listed historic site associated with the Underground Railroad.","full_desc":"A historic site in Oswego, New York, a National Underground Railroad Network to Freedom listing, Oswego Market House is filed here for what the record attaches to it.

Hall, is a historic market building located at Oswego in Oswego County, New York. It was built in 1835 and is a massive brick and stone structure overlooking the Oswego River. The structure originally housed several government entities including city hall. A new city hall was constructed in 1870 and completed in 1872. A section of the basement is believed to have been used as a jail. In 1864 the city sold it to the Oswego and Syracuse Railroad, that used it for the next 80 years as office and storage space. The railroad upgraded the building with a bracketed cornice and elaborate cupola.","img":"https://thumb.wikimedia.org/wikipedia/commons/thumb/1/15/Market_House_Oswego_NY_Nov_08.jpg/330px-Market_House_Oswego_NY_Nov_08.jpg?utm_source=en.wikipedia.org&utm_campaign=api&utm_content=thumbnail","score":78,"lat":43.45722222,"lon":-76.51083333},"counts":{"claims":0,"history":3,"legends":0,"entities":0,"sources":3}}
