Prospect Place, Historic mansion in Trinway, Ohio.
The 29-room residence contains solid brick interior walls and a two-inch mortar layer between floors as fire prevention structural elements.
George Willison Adams constructed this mansion in 1856 after relocating from Virginia to Ohio, where he operated an Underground Railroad station.
The mansion serves as the G.W. Adams Educational Center, promoting knowledge about the Underground Railroad and 19th-century architectural practices.
The building incorporated advanced systems for its time, including indoor plumbing with pressurized water and a copper tank cistern on the second floor.
The mansion features an early cooling system that channels basement air through ducts to upper floors and a specialized refrigeration setup for dairy products.
