The City of Glendale is a home rule municipality located in an exclave of Arapahoe County, Colorado, United States.

[5] Glendale is an enclave of the City and County of Denver and is the most densely populated municipality in Colorado.

The Four Mile House was one of the stage stops along the road, becoming a way station for freight wagons and a stock ranch.

[8] In the 1920s, the property at the northeast corner of Virginia Avenue and Colorado Boulevard was purchased; in 1933, a retail beer license was applied for and granted.

Later that year, an upper molar of a mammoth was found and donated to Denver's Museum of Natural History.

[5] Much of the city's limited space is devoted to commercial development, including both office and residential high rises.

Infinity Park is an event sports and entertainment complex adjacent to the Glendale municipal buildings and courthouse.

In July 2008, the city opened a 35,000-square-foot (3,300 m2) recreation and sports center that is managed by the YMCA of Metropolitan Denver.

The high-altitude training center was completed in February 2011, the final phase of the Infinity Park project.

Built in 1859 along Cherry Creek, the Four Mile House once served as a stage stop, wayside inn, and tavern for travelers on their way to Denver City via the Cherokee Trail.

Today Four Mile Historic Park houses a museum, summer camp, and events center.

The park is situated just outside Glendale's city limits, in the Washington Virginia Vale neighborhood of Denver.
