Built in 1898, the Holdsworth House/Aspenholme, Pines Lodge is significant as an intact example of a Shingle-style residence in a mountain resort setting. The building is further significant for its association with British members of the “English Colony” near Westcliffe, Custer County, Colorado, who brought British cultural traditions to the area beginning in the 1870s and extending into the first decades of the twentieth century. The lodge is also important, for its role as a lodge accommodating visitors to The Pines and serving as a focal point for the larger development.
