Major Henry McAllister, close associate of William J. Palmer, hired Philadelphia architect George Sommers to design and build this large red brick residence during 1873-1874.  The property is open to the public as a museum.

Described as a “tidy form-meets-function design” and a “little masterpiece of local modernity,” the building, designed by local architects Dietz Lusk and James Wallace, is an important example of Modernism in Colorado Springs.  The building is distinguished by its folded plate roof, cantilevered walls of glazed turquoise brick, and an integral exterior courtyard.

The 1892 Lindley-Johnson-Vanderhoof House is significant for its architecture as an excellent example of the Queen Anne style in Colorado Springs executed in stone and brick, as reflected in its steeply pitched gables, asymmetrical façade, use of multiple materials, circular tower and semi-decagonal bay, one-story porch extending into a terrace, and porte cochère. 

Constructed in 1900 for a prominent businessman, the house became part of the Colorado College campus in 1936.  It is associated with the development of north Colorado Springs and subsequently played a significant role in the college’s history, serving as the Student Union from 1937 to 1959. 

The 1928 Knights of Columbus Hall was the site of numerous social and entertainment activities in Colorado Springs, including fraternal organization meetings and social gatherings, and public assemblies, particularly for young people and high school students.  In 1937 it became the first home of the Pioneer Museum, now known as the Colorado Springs Pioneers Museum.

The 1900 Jackson House is associated with the development of the residential neighborhood directly east of Colorado College, an area of wealthy city residents who would became benefactors of the college.
