Westminster CO Historic Place
Westminster University, also known as Westminster Castle is listed on the National Register of Historic Places and overlooks the city of Denver.

Gold discovered in the South Platte River Valley in 1858 brought national attention to the area that would become Westminster, Colorado. The promise of fortune and the Land Act of 1862 encouraged many settlers from the east to make Colorado their home instead of heading on to California. Before the settlements came, wildlife like antelope and buffalo made their homes in this area. There is also evidence of Arapaho Indians near the Crown Point (Gregory Hill) area.

After the first permanent white settler, Pleasant DeSpain, built his home in 1870 on 160 acres (near what is now West 76th Avenue and Lowell Street), the area became known as DeSpain Junction and began attracting other settlers including horse breeder Edward Bruce Bowles who was instrumental in constructing the town's train depot in 1881. In 1885, Connecticut real estate developer C. J. Harris arrived in DeSpain Junction and began buying up land. Soon the town was renamed Harris, but was also known as Darell Park.

In 1891, construction began on the Westminster Castle, which can still be seen as of today at West 83rd Avenue and Federal Boulevard. By 1911, the town had incorporated and was renamed one final time to Westminster, in honor of Westminster University.
