The 4th & Vine Tower (formerly known as the Union Central Tower and Central Trust Bank Building) is a 151 m (495 ft) skyscraper in downtown Cincinnati, Ohio. It stands 31 stories tall, overlooking the Ohio River waterfront. It is easily one of the most recognizable buildings in the city's skyline, owing to the elaborate Hellenic architecture in the upper portion of the tower, which was modeled to resemble reconstructions of the Mausoleum at Halicarnassus. Few PNC Bank employees now work in the 4th & Vine Tower today, as most report to the newer PNC Center. PNC Bank has the signage rights to the building, but PNC Tower is not the official name. It is officially the 4th & Vine Tower. The signage on the building was "Central Trust" until sometime after the Scripps Building was completed in 1990.

The Greater Cincinnati Chamber of Commerce, doing business as the Cincinnati USA Regional Chamber, is a regional chamber of commerce. It is one of the nation's largest chambers of commerce, representing 4,000 businesses and nearly over 500,000 employees in southwestern Ohio, northern Kentucky and southeastern Indiana, also known as Greater Cincinnati, or the Cincinnati–Northern Kentucky metropolitan area. An award-winning membership organization, the Chamber has been recognized as national Chamber of the Year twice. The Cincinnati Chamber of Commerce was founded October 15, 1839, by 76 firms and private individuals who placed an ad in the Cincinnati Daily Gazette urging local businessmen to attend a meeting at the Young Men's Mercantile Library Association headquarters in the old Cincinnati College Building at Fourth and Walnut Streets. This Chamber's founding preceded the United States Chamber of Commerce, which held its first meeting in Cincinnati, by 73 years. The Chamber celebrated its 175 Anniversary in 2014. The Cincinnati Chamber of Commerce met in six different temporary locations until in 1876 they began the process that led to a permanent structure. The Chamber's Board of Real Estate Managers invited six architects to compete in a selection competition. Henry Hobson Richardson's design won and that building was erected in 1889. A fire in 1911 caused substantial damage to the building, leading to the discovery that only $90,000 of insurance was carried on the building, which had cost $772,674.05 to build, and so it could not be repaired. When the property was sold, much of the granite from the building was saved and stored in Oakley, Ohio. In 1967, Professor John Peterson at UC's University of Cincinnati College of Design, Architecture, Art, and Planning coordinated an effort to build a memorial to Henry Hobson Richardson out of the surviving stones. A design competition whose jury included's Richardson's grandson was held in 1968 and the design by student Stephen Carter (architect) was selected. The memorial was completed in 1972 and resides in Burnet Woods. According to Charles Ludwig, a journalist in the 1920s and 1930s for the Cincinnati Times-Star, up to that time, the Chamber had been involved in most of the city's significant developments since its creation. As Cincinnati grew and became an eight-county metropolitan area in the mid-1960s, the Chamber changed its name to the Greater Cincinnati Chamber of Commerce to reflect its regional representation of businesses throughout Southwestern Ohio, Northern Kentucky and Southeastern Indiana. It is now called The Cincinnati USA Regional Chamber. The phrase "Cincinnati USA" is used to indicate that Greater Cincinnati extends beyond just one U.S. city and state. Cincinnati USA is a region of 15 counties (In Ohio: Butler, Warren, Hamilton, Clermont and Brown Counties. In Kentucky: Boone, Kenton, Campbell, Gallatin, Grant, Pendleton and Bracken Counties. In Indiana: Franklin, Dearborn and Ohio Counties) located in three states (Ohio, Kentucky & Indiana).

Cincinnati ( SIN-si-NAT-ee) is a city in the U.S. state of Ohio and the county seat of Hamilton County. Settled in 1788, the city is located at the northern side of the confluence of the Licking and Ohio rivers, the latter of which marks the state line with Kentucky. The city is the economic and cultural hub of the Cincinnati metropolitan area. With an estimated population of 2,190,209, it is Ohio's largest metropolitan area and the nation's 29th-largest, and with a city population of 309,317, Cincinnati is the third-largest city in Ohio and 64th in the United States. Throughout much of the 19th century, it was among the top 10 U.S. cities by population, surpassed only by New Orleans and the older, established settlements of the United States eastern seaboard, as well as being the sixth-most populous city from 1840 until 1860. As a rivertown crossroads at the junction of the North, South, East, and West, Cincinnati developed with fewer immigrants and less influence from Europe than East Coast cities in the same period. However, it received a significant number of German-speaking immigrants, who founded many of the city's cultural institutions. By the end of the 19th century, with the shift from steamboats to railroads drawing off freight shipping, trade patterns had altered and Cincinnati's growth slowed considerably. The city was surpassed in population by other inland cities, particularly Chicago, which developed based on strong commodity exploitation, economics, and the railroads, and St. Louis, which for decades after the Civil War served as the gateway to westward migration. Cincinnati is home to three major sports teams: the Cincinnati Reds of Major League Baseball; the Cincinnati Bengals of the National Football League; and FC Cincinnati of Major League Soccer; it is also home to the Cincinnati Cyclones, a minor league ice hockey team. The city's largest institution of higher education, the University of Cincinnati, was founded in 1819 as a municipal college and is now ranked as one of the 50 largest in the United States. Cincinnati is home to historic architecture with many structures in the urban core having remained intact for 200 years. In the late 1800s, Cincinnati was commonly referred to as the "Paris of America", due mainly to such ambitious architectural projects as the Music Hall, Cincinnatian Hotel, and Shillito Department Store. Cincinnati is the birthplace of William Howard Taft, the 27th President and former Chief Justice of the United States.

The Ingalls Building, built in 1903 in Cincinnati, Ohio, is the world's first reinforced concrete skyscraper. The 16-story building was designed by the Cincinnati architectural firm Elzner & Anderson and was named for its primary financial investor, Melville E. Ingalls. The building was considered a daring engineering feat at the time, but its success contributed to the acceptance of concrete construction in high-rise buildings in the United States. It was converted to a hotel, the Courtyard by Marriott Cincinnati Downtown, in 2021.The Ingalls building is bordered by East 4th Street and Vine Street in the Cincinnati Central Business District.

The Cincinnati Skywalk was a series of walkways, primarily indoors and elevated, that allowed pedestrians to traverse downtown Cincinnati, Ohio.Built in segments starting in 1971, the 1.3-mile (2.1 km) skywalk was completed in 1997 at a total cost of more than $16 million. Since then, city leaders began to see the skywalk as a barrier to economic development, as it may decrease street-level and sidewalk pedestrian traffic. The skywalk was dismantled in stages from 2002 to 2020.
