Merchants Exchange Building (St. Louis)

The Planter's House Hotel was the name of three hotels in St. Louis, Missouri. The first operated from 1817, the second from 1841 to 1891, and the third until 1922.

The National Hotel was a historic hotel located at the southwest corner of 3rd and Market Streets in St. Louis, Missouri. The hotel originally opened in 1832 as Scott's Hotel, but this building was destroyed with a new hotel building built in 1847. Other names for this hotel included the New Scott's Hotel, United States Hotel, Germania House, Atlantic Hotel, St. Clair Hotel, and Rice Hotel. 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 Old St. Louis County Courthouse was built as a combination federal and state courthouse in St. Louis, Missouri. Missouri's tallest habitable building from 1864 to 1894, it is now part of Gateway Arch National Park and operated by the National Park Service for historical exhibits and events.

The Basilica of Saint Louis, King of France (French: Cathédrale Saint-Louis-Roi-de-France de Saint-Louis), formerly the Cathedral of Saint Louis, and colloquially the Old Cathedral, was the first cathedral west of the Mississippi River and until 1845 the only parish church in the city of St. Louis, Missouri. It is one of two Catholic basilicas in St. Louis, and it is named for King Louis IX of France, also the namesake for the city of St. Louis.The current structure (built 1831–1834) is located near the historic riverfront of St. Louis. It is surrounded by Gateway Arch National Park. However, the church is not part of the park. Because of the historical significance of the church, it was left intact while all neighboring buildings were demolished to make way for the Gateway Arch and related park. Rev. Nicholas Smith serves as Rector. The basilica serves as a personal parish church rather than a territorial parish church. It ranks 177th of 196 churches in number of Catholics per church in the Archdiocese of St. Louis. However, because of its historical significance (and its location along the Mississippi River near the iconic Arch), the basilica remains a popular church for marriage ceremonies in the archdiocese (ranking second of 196 churches) and a popular tourist destination.

The Marquette Building, also known as the Boatmen's Bank Building, is a historical building in downtown St. Louis. It was completed in 1914 at Broadway and Olive Streets, at 19 stories, designed by the St. Louis architecture partnership of Eames and Young. The building stands at 20 stories with a 2-story penthouse atop the 20th floor. A 1915 Annex, also designed by Eames and Young, was razed in 1998. The Marquette Building was added to the National Register of Historic Places the same year, and was redeveloped for condos in 2007. The building roof sports a small pool atop the eastern wing and a dog park/ relief area on the western wing, that are available to building residents.

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. Missouri is the only state to have two main Federal Reserve Banks (Kansas City also has a bank). Located in downtown St. Louis, the St. Louis Fed is the headquarters of the Eighth Federal Reserve District, which includes the state of Arkansas and portions of Illinois, Indiana, Kentucky, Mississippi, the eastern half of Missouri and West Tennessee. 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 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.

One Metropolitan Square, also known as Met Square, is an office skyscraper completed in 1989, located in downtown St. Louis, Missouri. At 180.7 m (593 ft), it is the tallest building in the city, and second tallest building in Missouri behind the One Kansas City Place in Kansas City by only 31 feet. Major tenants include architecture firm Hellmuth, Obata and Kassabaum, which also designed the building, the Bryan Cave law firm, the Evans & Dixon law firm, the Brown & Crouppen law firm, and the Better Business Bureau. The building was constructed by McCarthy Building Companies, Inc., the largest general contractor in St. Louis. In early May, 2014, a DJI Phantom quadcopter drone crashed into the building.

The International Fur Exchange Building, at 2 S. Fourth St. in St. Louis, Missouri, was listed on the National Register of Historic Places in 1998. The original building is a seven-story commercial building, on a 125 by 150 feet (38 m × 46 m) plan, designed by architect George W. Hellmuth. It was built during 1919–20.It has also been known as the Fouke Fur Company Building. It was site of fur auctions. The Fouke Fur Company held all rights, by an exclusive contract with the United States Government, "for the processing and sale of all sealskins and foxskins taken from Government herds on the Pribilof Islands in the Bering Sea. In addition, from 1920- 1925 and again from 1934-1956." Public auctions of its fur seal pelts were held here.A ten-story addition on the south, added in 1958, has compatible design. The building experienced some demolition in 1997, mostly on the building's interior, with removal of salvageable materials. However, some of the building maintained external damage during the demolition. In 1997, Drury Hotels acquired the International Fur Exchange Building property, and, along with the Thomas Jefferson Building and American Zinc building, saved them from being demolished and renovated all three into a single building, now called the Drury Plaza Hotel at the Arch. During renovation, all three buildings were added to the National Register of Historic Places.

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.

Barnum's St. Louis Hotel was a historic 6-floor hotel built in 1854. The Barnums were a family of hotel keepers who had run the famous Barnum's Hotel in Baltimore. This building was located at the 2nd and Walnut Streets in St. Louis, Missouri, and has been considered to be St. Louis' first high-rise building. The hotel was designed by architect George I. Barnett. The famous former slave Dred Scott worked as a porter here from 1857 until his death. Dred Scott's new owners had freed him two months after the U.S. Supreme Court decision. Scott became a local celebrity, greeting visitors at the hotel until he died of tuberculosis on September 17, 1858.Famous guests included Henry Clay and Illinois Governor Richard Yates.The hotel was demolished in 1890.

Gateway Arch National Park is an American national park located in St. Louis, Missouri, near the starting point of the Lewis and Clark Expedition. In its initial form as a national memorial, it was established in 1935 to commemorate: the Louisiana Purchase and subsequent westward movement of American explorers and pioneers; the first civil government west of the Mississippi River; and the debate over slavery raised by the Dred Scott case.The national park consists of the Gateway Arch, a steel catenary arch that has become the definitive icon of St. Louis; a park along the Mississippi River on the site of the earliest buildings of the city; the Old Courthouse, a former state and federal courthouse where the Dred Scott case originated; and the 140,000 sq ft (13,000 m2) museum at the Gateway Arch. It is the smallest national park in the United States at 91 acres (37 ha), less than 2% the size of the next-smallest, Hot Springs National Park. The immediate surroundings of the Gateway Arch were initially designated the Jefferson National Expansion Memorial (a national memorial) by executive order on December 21, 1935. The Gateway Arch was completed on October 28, 1965. The park is maintained by the National Park Service (NPS). The area surrounding the arch was redesignated as the "Gateway Arch National Park" (a national park) in 2018. This change has been highly controversial due to the nature of the site ("national parks" typically involve significant natural landscapes and significant opportunities for nature recreation, whereas sites that have primarily historical and architectural significance are usually given other NPS designations). Several publications noted that the addition of Gateway Arch as a national park eroded the significance associated with the "national park" designation, and some suggested that the change was made in order to promote tourism rather than to conserve a nature area.
