It is known in later years as Cahill's Fish Market.","why_significant":"The nomination calls the building a landmark of Oswego Harbor and an architecturally distinctive limestone store that has lived through many phases of the city's commercial history. Built in 1828, the year after the Oswego and Syracuse Canal connected Lake Ontario to the Erie Canal, it served ship chandlers, shipping lines and a warehouse operation. It is one of the few surviving riverfront structures and a functioning enterprise tied to the historic harbor.","narrative":"Stepped gables and ivy-covered limestone walls make this four-story building a recognizable feature of Oswego Harbor. Built in 1828 on the west bank of the Oswego River, it was designed as two attached stores, each three bays wide with its own entrance. Jonathan Walton bought the lot in 1827, and the merchants Walton and Willett used the south half as an office while a ship chandlery rented the north half. Later occupants included sailmakers, a newspaper, a customs collector, the Ontario Steamboat Company and the Northern Transportation Company. A railroad spur laid along Water Street in the 1860s raised the street and buried the first story on the west side. After 1885 it served as a warehouse for a neighboring sash and blind factory, and it stood largely empty in the early twentieth century. A fish market has operated there since 1945. Most nearby riverfront buildings have been demolished, leaving this store as a rare link to the harbor's commercial past.","period_of_significance":"1828","architect_builder":"Builder not recorded; the form suggests it may have been J.C.
