Why it's listed
Glamorgan is a three-story mansion on a landscaped terraced rise in Alliance, Ohio, set roughly 800 feet back from Union Avenue. Built between 1903 and 1908 for Colonel William H. Morgan, Sr., president of the Morgan Engineering Company, it was designed by Cleveland architects Paul Searles and Willard Hirsh. The walls are rusticated blue Vermont marble trimmed in white marble, with a red vitrified tile roof. The east front imitates a late medieval Welsh baronial hall, with a crenelated parapet, a square tower with corner turret, a Tudor-style entrance loggia and a porte cochere. Inside, rooms were finished in Renaissance Revival, Empire, Tudor and French Renaissance styles. The house also had steel conduit and more than 1,200 electrical outlets. It was listed as a remarkable example of the eclectic mansions built by industrialists. The name comes from Glamorganshire, Wales, birthplace of the Morgan company's founder. The house recalls a period when great wealth allowed such castles to be built.
Significance in brief: The nomination calls it a remarkable example of the great eclectic houses of the late-nineteenth-century industrialists. It combines a Welsh baronial castle appearance with advanced mechanical and electrical systems. It also preserves an image of the era when concentrated wealth made such castles possible.
