Late 19th century and early 20th century Colorado Midland Railroad began service in the town in 1885. Chicago, Rock Island and Pacific Railroad service began in 1889. Trolleys ran to Manitou Springs the following year. After the Cripple Creek gold discovery in 1891, the people who made a fortune from the gold rush and industry built large houses on Wood Avenue, then in the undeveloped downtown area of Colorado Springs. Several large stone buildings like Colorado College, St. Mary's Church, the first Antlers Hotel, the library, and the county courthouse were built on wide streets, in anticipation of significant population growth. By 1898, the city that had grown through
annexations was designated into quadrants by the north–south Cascade Avenue and the east–west Washington/Pike's Peak avenues, along with voting precincts 27-41 and five wards with the fire alarm zones. Inventor
Nikola Tesla built and operated his wireless power
experimental station in 1899 on Knob Hill, near the current intersection of Foote and Kiowa Streets. Governor
James Hamilton Peabody sent troops to Colorado City in 1903 to settle a miner's strike. They set up Camp Peabody at what became the 1903
Colorado Labor War. According to Mrs. Gilbert McClurg, reported in the Colorado Springs Gazette, General Palmer visited the west bank of Monument Creek and located a lost mineral spring so that it was included in his plans for Monument Valley Park. By 1905, the lake at
Monument Valley Park was built at a cost of US$750,000 (), the YMCA building was built for $100,000 (), and Broadmoor Country Club built one of the city's two polo fields. There was a plan in 1911 plan to build a Colorado Springs Union Depot to consolidate the two railroad passenger depots, but it was never completed. A zoological park was built along Cheyenne Creek, near Bear Creek Road (now Eighth Street), by 1916 and the
Cheyenne Mountain Zoo was built in 1925 above
The Broadmoor resort on the
Cheyenne Mountain Zoo Road. In 1919, William Kennon Jewett deeded the Colorado Springs Golf Club's golf course to the City of Colorado Springs. Aircraft flights to the Broadmoor neighborhood fields began in 1919, the Alexander Airport (later called
Nichols Field) north of the city opened in 1925 and land was purchased in 1927 for the first
Colorado Springs Municipal Airport. Successful mine owner
Winfield Scott Stratton funded the
Myron Stratton Home for housing itinerant children and the elderly, donated land for City Hall, the
main post office, the Courthouse, and a park; he also greatly expanded the city's trolley car system and built the Mining Exchange building.
Spencer Penrose and his wife, over the course of their lives, financed construction of
The Broadmoor resort (1918),
Pikes Peak Highway,
Cheyenne Mountain Zoo (1921),
Will Rogers Shrine of the Sun (1937), made a significant donation to what is now known as Penrose-St Francis Health Services, and established the
El Pomar Foundation, which still oversees many of his contributions in Colorado Springs today. A bronze sculpture of Palmer on a horse was unveiled in 1929. Many of the large homes in Colorado Springs were made into apartment houses or became boarding houses during the
Depression of the 1930s and when there was a housing shortage during
World War II. Some homes were also converted into office space. Silver Cascade Falls,
Helen Hunt Falls, N. Cheyenne Canyon Road and other land in North Cheyenne were purchased and donated to the city in 1907 by William Jackson Palmer. The cañon was considered by the Park Commission to be "by far the grandest and most popular of all the beautiful cañons near the city." After a lull between 1917 and 1946, annexation began in earnest. Some examples of annexed areas are: Pleasant Valley (1950), Knob Hill (1952), Austin Bluffs (1958–1965), Pike View (1962), Papeton (1968), Woodmen Valley (1969), and Stratton Additions (1966–1971). Between 1960 and 1970 divisions of Cheyenne Mountain, Elmere, Black Forest-Peyton, Fountain, Pikes Peak and Monument were annexed into Colorado Springs, resulting in an increased population of 37,500 by 1970. Broadmoor and Skyway were annexed, without a vote of its residents, before the state's
Poundstone Amendment (1974) was enacted. Briargate was annexed in 1982.
Parks The first city park in Colorado Springs, included in the initial town plans in 1871, is Acacia Park. It was initially called Acacia Square or North Park. General William Jackson Palmer donated land to establish Acacia and additional parks, including: Antlers Park, Monument Valley Park, North Cheyenne Cañon,
Palmer Park, Pioneer Square (South) Park,
Prospect Lake and
Bear Creek Cañon Park. He donated a total of 1,270 acres of land, some of which was also used for scenic drives, tree-lined roadways and foot and bridle paths. The Perkins heirs donated Garden of the Gods to the city in 1909.
Military installations The city purchased land at the southern border of the city and donated it to the War Department. After the
Pearl Harbor attack, the U.S. Army established
Camp Carson, named for General
Kit Carson, near the southern borders of the city as a training facility in preparation for World War II.
Colorado Springs Municipal Airport was used by the Colorado Springs Army Air Base and was assigned to the Air Force in 1942 for photo reconnaissance training. It was renamed
Peterson Field for Lt. Edward J. Peterson who died during a takeoff from the field. After World War II there was little military presence in the city. Camp Carson had only 600 soldiers. When the
Korean War began there was an influx of military personnel. In 1951, the United States Air Defense Command moved to Colorado Springs and opened
Ent Air Force Base.
Ent Air Force Base was shut down and in 1977 was converted into the
United States Olympic Training Center. Peterson Field was renamed Peterson Air Force Base and was permanently activated.
Air Force Space Command is located on Peterson AFB. In 1972, the city's first
National Register of Historic Places designation was the
1903 El Paso County Courthouse. The first designated historic district was the 1979
Rock Ledge Ranch Historic Site. In 1977, most of the former Ent Air Force Base became the first
US Olympic Training Center, and the
US Olympic Committee moved there in 1978. In 2012, the
Waldo Canyon fire destroyed 346 homes and killed two people in the city. ==See also==
