The form calls it the only important old house remaining in the city that is in good condition and still occupied by its owner.","narrative":"Built in 1876 on a hillside lot at 305 Walnut Street in East Liverpool, this brick house was the home of Cassius Clark Thompson, who was only 25 when he built it. He chose the site for its view of the Ohio River, a block away. The house is a Victorian design with Italianate details, including bracketed cornices, stone sills and lintels, hooded windows and a three-story tower with a mansard roof and wrought-iron railing. Inside are a central hall with a graceful stairway, high ceilings, transoms over every door and an Italian marble mantel. Thompson led the C. C. Thompson Pottery Company, which grew from making Rockingham and yellow ware to cream-colored and semi-porcelain goods, and he is credited with several pottery inventions. The lot also holds an old modeling shop and a cooper shop from the pottery days. The house was listed for its link to the local pottery industry and for its architecture.","period_of_significance":"1876","architect_builder":"Cassius Clark (C. C.)
