The City of Westminster is a home rule municipality located in Adams and Jefferson counties, Colorado, United States.

The Westminster Municipal Center is located 9 miles (14 km) north-northwest of the Colorado State Capitol in 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 Homestead Act of 1862 encouraged many pioneers from the east to settle in Colorado rather than continue on to California.

[7] Westminsters' first permanent settler was Kentucky farmer Pleasant DeSpain, who built his home in 1870 on 160 acres (near what is now West 76th Avenue and Lowell Street).

In 1911, Harris voted to incorporate as a city and changed its name to Westminster, in honor of the university which is now on the National Register of Historic Places.

[11] Westminster City Hall features a 14-story bell tower topped by a pyramid shaped steel mesh structure.

The 130-foot spire, which is widely known and referenced as a community landmark, was first conceptualized as a symbolic tie and tribute to the clock tower of Westminster Palace in England known as Big Ben.

It is bordered to the north by Broomfield, to the northeast by Thornton, to the east by Northglenn and Federal Heights, to the southeast by Sherrelwood, Twin Lakes and Berkley, and to the south by Arvada.

[18] RTD opened the B Line to the public in 2016 which brings commuter rail service between downtown Denver and Westminster Station.

The 6 miles of commuter rail transports riders from the historic center of Westminster to the dynamic Union Station Transit Center where they can connect to the C/D, E, and W light rail lines, the A Line to Denver International Airport, as well as Local and Regional buses, and the FreeMallRide and FreeMetroRide downtown shuttles.

Downtown Westminster intersects directly with the new U.S. 36 Bikeway linking the largest trail system in the Front Range with over 145 miles.

[26] Westminster is home to The Orchard Town Center, an outdoor mall featuring over 90 speciality retailers, dining and entertainment located at the intersection of I-25 and 144th Avenue.
