The Boyle House is one of the oldest homes in Santa Fe, with a long sequence of ownership. While the exact date of construction and original ownership are unknown, tree-ring samples from the home’s vigas date the structure to about 1730. Once a substantial casa grande, the property was divided in the late nineteenth century into separate north and south houses, rejoined decades later, and enlarged by various owners. The house features massive four-foot-thick adobe walls, ceilings made of split cedar rajas and vigas, and Territorial Style elements such as a portal extending along the rear of the building, fireplaces with mantels, paneled wood doors, and a bay window.
