The Merchants Exchange Building was a building at Third Street at Chestnut and Pine in St. Louis, Missouri, from 1875 to 1958 that housed the St. Louis Merchants Exchange and hosted the 1876 Democratic National Convention. The building was designed by Francis Lee and Thomas Annan who placed second in a competition for the structure (the winner was George I. Barnett but his work was considered too expensive. The building was the second Merchants Exchange on the location. The first building was built in 1857. During the American Civil War members of the exchange split along North-South lines. The Exchange merged back together after the war. The $2 million venue measured 235 by 187 ft (72 by 57 m) by 187 feet (57 m) and was actually two separate buildings. The second and third floors of the western half of the building had an iron truss system that supported the roof and created the largest open indoor space in the United States at the time of its construction (235 feet long and 98 feet (30 m) wide and 65 feet (20 m) tall) and thus was chosen for the 1876 convention which was the first Democratic or Republican national convention west of the Mississippi River. At the same time of its construction the Merchants Exchange built the Eads Bridge across the Mississippi River.The building was torn down in 1958. Part of the Adam's Mark Hotel was built in its location. In 2008 the Adams Mark announced plans to become a Grand Hyatt. The Merchants Exchange founded in 1836 was the first commodity trading exchange in the United States—predating the Chicago Board of Trade. In its early years it was referred to as the Chamber of Commerce. Articles about the 1876 Convention referred to it as the Chamber of Commerce. After vacating its downtown location, it was evicted in 1995 from its new location by eminent domain when St. Louis expanded the St. Louis Science Center. The Exchange made a last gasp in 2000/2001 to conduct computerized trading of future trading of freight on the Mississippi River. It has quietly ceased operation.

The Federal Reserve Bank of St. Louis is one of 12 regional Reserve Banks that, along with the Board of Governors in Washington, D.C., make up the United States' central bank.

It has branches in Little Rock, Louisville and Memphis. Its building, at 411 Locust Street, was designed by St. Louis firm Mauran, Russell & Crowell in 1924. The Eighth District serves as a center for local, national and global economic research, and provides the following services: supervisory and regulatory services to state-member banks and bank holding companies; cash and coin-handling for the District and beyond; economic education; and community development resources.

The National Hotel was a historic hotel located at the southwest corner of 3rd and Market Streets in St. Louis, Missouri.

The hotel was five stories high and was known as the St. Louis's most luxurious hotel at the time. The hotel was included in the federal Historic American Buildings Survey, but this did not prevent it from being demolished in 1948. Notable guests at this hotel included Abraham Lincoln, Daniel Webster, and Jefferson Davis.The first public transit omnibus line for St. Louis was established in 1843. It ran from the old National Hotel to the North St. Louis ferry landing at Madison Street.

The Grand Opera House was the name of two theatres located in St. Louis, Missouri on the same property on the south side of Market Street between Broadway and Sixth Streets. The first theatre, originally known as the Varieties Theatre, opened in 1852 and went by several different names, including the Grand Opera House, during its thirty-two year existence. After it was destroyed by fire in November 1884, a second theatre, known from its inauguration as the Grand Opera House, was built on the site of the first theatre and opened just 10 months after the destruction of the first theatre in September 1885. In 1935 the second Grand Opera House was renamed the Grand Theatre when it became part of a chain of a burlesque circuit of theaters. It operated under that name into the early 1960s. In 1963 the theatre was demolished to make room for Busch Memorial Stadium.

The building is on the National Register of Historic Places and designated an official landmark by the City of St. Louis.It was listed on the National Register in 2000.

The Battle of St. Louis (Spanish: Batalla de San Luis), also known as the Battle of Fort San Carlos, was an unsuccessful attack by British-allied Indians on St. Louis (a French settlement in Spanish Louisiana, founded on the West Bank of the Mississippi River after the 1763 Treaty of Paris) on May 26, 1780, during the American Revolutionary War. A Loyalist fur trader led a large force of Indians and attacked the settlement. Fernando de Leyba, the Lieutenant Governor of Upper Louisiana, led the local militia to fortify the town as best as they could and successfully withstood the attack. On the opposite bank of the Mississippi, a second simultaneous attack on the nearby Patriot outpost of Cahokia was also repulsed. The retreating Indians destroyed the crops and took captive civilians outside the protected area. The British failed to defend their side of the river and, thus, effectively ended any attempts to gain control of the Mississippi River during the war.

The Southern Hotel was a historic hotel located at the corner of 4th Street and Walnut Street and stretching between 4th and 5th Streets in St. Louis, Missouri. The building was built at the location of the Old Southern Hotel which burned in 1877. This 1877 hotel fire and the loss of life that occurred here made this the worst hotel disaster in St. Louis history. The new Southern Hotel had white marble, extensive fresco work, a rotunda, and a wide promenade. The hotel was owned by Robert G. Campbell who had a close friendship with President Grant. The hotel was closed in 1912 as newer and larger hotels were built further west. The hotel was torn down in 1933. The National Register of Historic Places, the official United States list of the historic places worthy of preservation, was not authorized until over 30 years later in 1966.
