St. Louis () is the second-largest city in Missouri, United States. It is located near the confluence of the Mississippi and the Missouri Rivers. In 2020, the city proper had a population of 301,578, while its bi-state metropolitan area, which extends into Illinois, had an estimated population of over 2.8 million, making it the largest metropolitan area in Missouri and the second-largest in Illinois. Before European settlement, the area was a regional center of Native American Mississippian culture. St. Louis was founded on February 14, 1764, by French fur traders Gilbert Antoine de St. Maxent, Pierre Laclède and Auguste Chouteau, who named it for king Louis IX of France, and it quickly became the regional center of the old Illinois Country. In 1764, following France's defeat in the Seven Years' War, the area was ceded to Spain. In 1800, it was retroceded to France, which sold it three years later to the United States as part of the Louisiana Purchase; the city was then the point of embarkation for the Corps of Discovery on the Lewis and Clark Expedition. In the 19th century, St. Louis became a major port on the Mississippi River; from 1870 until the 1920 census, it was the fourth-largest city in the country. It separated from St. Louis County in 1877, becoming an independent city and limiting its political boundaries. In 1904, it hosted the Louisiana Purchase Exposition and the Summer Olympics. A global city with a metropolitan GDP of more than $160 billion in 2017, metropolitan St. Louis has a diverse economy with strengths in the service, manufacturing, trade, transportation, and tourism industries.

The Civil Courts Building is a landmark court building used by the 22nd Judicial Circuit Court of Missouri in St. Louis, Missouri. The building with its pyramid shaped roof is prominently featured in the center of photos of the Gateway Arch from the Illinois side as its location on the Memorial Plaza is lined up in the middle directly behind the Old Courthouse. The building was part of an $87 million bond issue ratified by voters in 1923 to build monumental buildings along the Memorial Plaza which also included Kiel Auditorium and the Municipal Services Building. The Plaza and the buildings were part of St. Louis's City Beautiful plan. It replaced the Old Courthouse as the city's court building and its construction prompted the descendants of the founding father Auguste Chouteau to unsuccessfully sue the city to get the Old Courthouse back since the stipulation was that it was to always be the courthouse. The pyramid roof on the top was designed to resemble the Mausoleum at Halicarnassus which was one of the Seven Wonders of the Ancient World. It features 32 Ionic columns. Each of the columns have 6 fluted drums, and a cap, and are about 42 feet (13 m) high, 5+1⁄2 feet in diameter. They are made of Indiana limestone.The roof is made of cast aluminum and is topped by two 12-foot (3.7 m) high sphinx-like structures with the fleur-de-lis of St. Louis adorned on the chests.

Rebeck.Some architectural elements from the building have been removed in renovations and taken to the Sauget, Illinois storage site of the National Building Arts Center.During St. Louis PrideFest, the building has lit its columns up in a rotating rainbow pattern.
