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.
The pyramid roof on the top was designed to resemble the Mausoleum of Maussollos which was one of the Seven Wonders of the Ancient World. It features 32 Ionic columns (8 on each side). Each of the columns have 6 fluted drums, and a cap, and are about 42 feet (13 m) high, 5½ 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. These sphinx-like creatures were sculpted by Cleveland sculptor, Steven A. Rebeck.
