The Baker Historic District is a well-preserved middle class neighborhood developed from the 1870s to the 1920s. The greatest period of development was the late 1880s and the early 1890s as exemplified by the great variety of Queen Anne houses within the district. Its architectural interest is enhanced by the large number (19) of houses designed by Denver architect William Lang, well known for his fanciful and imaginative residential designs, and his partner, Marshall Pugh.
