Location of Denver in the United States

The history of skyscrapers in Denver began with the completion of the Equitable Building in 1892; this building, rising 143 feet (44 m) and nine floors, was the first high-rise in Denver.^[4] The title of the city's "first skyscraper" is usually given to the Daniels & Fisher Tower, which rises 325 feet (99 m) and was completed in 1910.^[5][6] The city went through a large building boom that lasted from the early 1970s to the mid-1980s. During this time, 21 of the city's 27 tallest buildings were constructed, including Republic Plaza, 1801 California Street, and the Wells Fargo Center. The city is the site of eight skyscrapers over 492 feet (150 m) in height, including two which rank among the tallest in the United States. Overall, the skyline of Denver is ranked (based upon existing and under construction buildings over 492 feet (150 m) tall) second in the Mountain States (after Las Vegas) and seventeenth in the United States.^[A] As of June 2018^[update], there are 201 completed high-rises in the city.^[7]

The tallest building recently completed in Denver is the Four Seasons Hotel and Tower, which rises 45 stories and 641 feet (195 m).^[8] It now stands as the fourth-tallest building in Denver as well as the city's tallest residential tower. The 1144 Fifteenth office tower rises just over 600 feet at over 40 stories making it the fifth-tallest building in Denver upon completion early 2018. Denver is currently experiencing a mid-high rise residential building boom with several large projects under construction throughout the city and more than 20 new projects breaking ground downtown Denver, golden triangle and RINO in 2023.

Like with many large cities in the United States, Denver's CBD and the adjacent neighborhoods were blighted with the presence of many open parking lots in the 1970s and '80s. Recent focus to redevelop these open lots and increase density/activity in the city's core have been hugely successful as many of these lots are today being turned into large residential, retail and commercial developments. This is especially true around the newly redeveloped and highly popular Union Station area in Denver's LoDo (Lower Downtown) neighborhood. What used to be open land, parking lots, warehouses and rail yards as recently as the turn of the century is now several city blocks of new residential and commercial buildings as well as a new RTD underground bus terminal, rail platforms/pavilions and a park. There are also improved pedestrian friendly connections to the RiNo (River North), Five Points, Auraria and Highland neighborhoods from the new development. Historic Union Station itself has been fully renovated and turned back into a travel and activity hub. It now includes the Denver Amtrak station, a new boutique hotel and several restaurants, bars & shops all centered on the large Great Hall inside and a public plaza outside along Wynkoop Street. In April 2016 the University of Colorado A-Line commuter train began service directly connecting Union Station and downtown Denver to Denver International Airport and the airport's new 500-plus-room Westin Hotel & conference center.
