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.

International Hat Company, formerly named the International Harvest Hat Company, was a St. Louis, Missouri-based manufacturer of commercial hats and military helmets. The company was one of the largest hat manufacturers in the United States and, at one time, the largest manufacturer of harvest hats in the world. It is best remembered for its design and mass production of tropical shaped, pressed fiber military sun helmets for service members of the United States Army, Marines, and Navy during and after World War II. Additionally, the American owned company was a major producer of harvest hats, straw hats, fiber sun hats, enameled dress hats, baseball caps, and earmuffs throughout most of the 20th century. However, it is the International Hat military sun helmets that have become the most notable collector's items. Established in 1917 as a private corporation, the company began with a single product line of harvest straw hats. By the late 1930s, the company had expanded into fiber pressed sun hats and leather harvest hats. During World War II, International Hat developed and produced several models of military sun helmets, including a model with rudimentary ventilation. After the war, the company became interested in plastic molding injection, moving increasingly away from pressed fiber. In the 1950s, General Fibre Company, a subsidiary of International Hat, changed its name to General Moulding Company to reflect these production changes in basic materials. By the 1960s, International Hat was mostly producing baseball caps, straw hats, earmuffs, plastic helmets, and plastic sun hats. During this era of expansion, the company had a proclivity for building its factories in small rural cities, often becoming the largest employer and economic backbone of those communities. On several occasions, International Hat donated land or facility equipment for the creation of municipal parks located adjacent to one of its factories, namely for the purpose of benefiting employees, their families, and the local community.After sixty-one years of business, the company was sold in 1978 to Interco, Inc., where it continued operating as a subsidiary. In 1988, Interco was the target of a hostile takeover bid. Consequently, International Hat was divested the following year to Paramount Cap Company, as part of a debt restructuring plan instituted by the parent company. However, Interco subsequently went bankrupt in 1991, after selling 16 of its 20 subsidiaries. Although International Hat was liquidated, several of its original factories are still in operation by other hat companies in Southeastern Missouri. Additionally, one of International Hat's warehouses in the historic district of Soulard, Missouri has been added to the National Register of Historic Places. International Hat operated the historical building from 1954 to 1976. It is presently used as a senior and disabled living facility.

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.
