The Moyle House and Indian Tower are significant examples of vernacular architecture from Alpine’s early settlement period. The Indian Tower is the only known structure of its type in Utah built to protect a single homestead. Constructed circa 1860-66 to watch for and provide defense against American Indians during the Black Hawk War of 1865-68, the tower was built of local river rock by owner and stone mason John Rowe Moyle. Its utilitarian design matched that of the original dugout house and the good cellar built circa 1858. In 1859-60, Moyle built a small stone house over the original dugout house. In 1917, Joseph Edward Moyle, the youngest son of John and Philippa Moyle, built a large addition on the south side of the house and expanded the attic in the then-popular Bungalow/Arts and Crafts style. In recent years, the tower has been substantially rebuilt following historical photographs, and the house and food cellar, the only other original features on the site, are also being carefully restored.
