Westminster is a Home Rule Municipality in Adams and Jefferson counties in the U.S. state of Colorado. Westminster is a northwest suburb of Denver. The Westminster Municipal Center is located 9 miles (14 km) north-northwest of the Colorado State Capitol. As of the 2010 census the population of Westminster was 106,114,  and as of 2016 the estimated population was 113,875.  Westminster is the seventh most populous city in Colorado and the 237th most populous city in the United States. Westminster is a part of the Denver-Aurora-Lakewood, CO Metropolitan Statistical Area and the Denver-Aurora-Boulder Combined Statistical Area. In July 2006, it was ranked as the 24th best place to live in the USA by Money magazine. 
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.
