Winter Garden at Exposition Hall

The Point Park Civic Center was a proposed civic center for downtown Pittsburgh, Pennsylvania, United States, where the confluence of the Allegheny and Monongahela Rivers forms the Ohio River. Frank Lloyd Wright designed the structure on a commission from Edgar J. Kaufmann in the late 1940s. Wright initially envisioned a circular building more than 1,000 feet (300 m) in diameter and 175 feet (53 m) tall. The structure, containing an opera house, sports arena, three movie theaters, and a convention hall, was wrapped by a spiraling strip of road. The plan expressed Wright's insistence on bringing the automobile into the social setting. It did not find favor with Pittsburgh authorities. To make the design more palatable to its audience, Wright developed a radically different proposal for a monolithic tower supporting bridges across the Allegheny and Monongahela. This too was unsuccessful, and none of Wright's work for the site was ever built. The site is now occupied by Point State Park. Elements of Wright's plan contain similarities to other Wright designs, including the Solomon R. Guggenheim Museum and his unrealized plans for Monona Terrace.

Point State Park (locally known as The Point) is a Pennsylvania state park on 36 acres (150,000 m2) in Downtown Pittsburgh, Allegheny County, Pennsylvania, USA, at the confluence of the Allegheny and Monongahela rivers, forming the Ohio River. Built on land acquired via eminent domain from industrial enterprises in the 1950s, the park opened in August 1974 when construction was completed on its iconic fountain. Pittsburgh settled on the current design after rejecting an alternative plan for a Point Park Civic Center designed by Frank Lloyd Wright. The park also includes the outlines and remains of two of the oldest structures in Pittsburgh, Fort Pitt and Fort Duquesne. The Fort Pitt Museum, housed in the Monongahela Bastion of Fort Pitt, commemorates the French and Indian War (1754–63), in which the area soon to become Pittsburgh was a major battlefield. It was designated a National Historic Landmark in 1960 for its role in the strategic struggles between Native Americans, French colonists, and British colonists, for control of the Ohio River watershed.

Three Rivers Park is a public urban waterfront park along the Allegheny, Monongahela, and Ohio Rivers in Pittsburgh, Pennsylvania. The park, under development since 2000, is currently defined by the boundaries of the West End Bridge over the Ohio River, the 31st Street Bridge over the Allegheny River, and the Hot Metal Bridge over the Monongahela River. The wishbone-shaped loop of Three Rivers Park encompasses the Pittsburgh Peninsula and Point State Park at its center, and spans over 13 miles of interconnected trails and green space with over 800 acres of public open space.

Fort Duquesne (, French: [dykɛn]; originally called Fort Du Quesne) was a fort established by the French in 1754, at the confluence of the Allegheny and Monongahela rivers. It was later taken over by the British, and later the Americans, and developed as Pittsburgh in the U.S. state of Pennsylvania. Fort Duquesne was destroyed by the French, prior to British conquest during the Seven Years' War, known as the French and Indian War on the North American front. The British replaced it, building Fort Pitt between 1759 and 1761. The site of both forts is now occupied by Point State Park, where the outlines of the two forts have been laid in brick.

The Battle of Fort Duquesne was British assault on the eponymous French fort (later the site of Pittsburgh) that was repulsed with heavy losses on 14 September 1758, during the French and Indian War. The attack on Fort Duquesne was part of a large-scale British expedition with 6,000 troops led by General John Forbes to drive the French out of the contested Ohio Country (the upper Ohio River Valley) and clear the way for an invasion of Canada. Forbes ordered Major James Grant of the 77th Regiment to reconnoiter the area with 850 men. Grant, apparently on his own initiative, proceeded to attack the French position using traditional European military tactics. His force was out-maneuvered, surrounded, and largely destroyed by the French and their native allies led by François-Marie Le Marchand de Lignery. Major Grant was taken prisoner and the British survivors retreated fitfully to Fort Ligonier. After repulsing this advance party, the French, deserted by some of their native allies and vastly outnumbered by the approaching Forbes, blew up their magazines and burnt Fort Duquesne. In November the French withdrew from the Ohio Valley and British colonists erected Fort Pitt on the site. Forbes commanded between 5,000 and 7,000 men, including a contingent of Virginians led by George Washington. Forbes, very ill, did not keep up with the advance of his army, but entrusted it to his second in command, Lt. Col. Henry Bouquet, a Swiss officer commanding a battalion of the Royal American Regiment. Bouquet sanctioned a reconnaissance of Fort Duquesne by Major James Grant of Ballindalloch.

The Manchester Bridge, also known as the North Side Point Bridge, was a steel Pratt truss bridge that spanned the Allegheny River in Pittsburgh, Pennsylvania.

The Fort Pitt Block House (sometimes called Bouquet's Blockhouse or Bouquet's Redoubt) is a historic building in Point State Park in the city of Pittsburgh. It was constructed in 1764 as a redoubt of Fort Pitt, making it the oldest extant structure in Western Pennsylvania, as well as the "oldest authenticated structure west of the Allegheny Mountains".

Fort Pitt Museum is an indoor/outdoor museum that is administered by the Senator John Heinz History Center in downtown Pittsburgh, Allegheny County, Pennsylvania in the United States. It is at the confluence of the Monongahela and Allegheny Rivers, where the Ohio River is formed. Fort Pitt Museum is surrounded by Point State Park, a Pennsylvania state park named for the geographically and historically significant point that is between the rivers. This piece of land was key to controlling the upper reaches of the Ohio River Valley and western Pennsylvania, before, during and after the French and Indian War as well as the American Revolution. The museum is in a recreated bastion of Fort Pitt, which was originally built in 1758 by the British. An outline of Fort Duquesne is nearby. The historical focus of the museum is the role that Fort Pitt played during the French and Indian War. The museum also features detailed information on Fort Pitt's role during the American Revolution, the Whiskey Rebellion and the founding of Pittsburgh. The museum was established and operated by the Pennsylvania Historical and Museum Commission until its closure in August 2009 from state budget cuts. The Heinz Center took over the operation of the museum and reopened it in April 2010.

The Point Bridge was a steel cantilever truss bridge that spanned the Monongahela River in Pittsburgh, Pennsylvania.

The Fort Pitt Bridge is a steel, double-decked bowstring arch bridge that spans the Monongahela River near its confluence with the Allegheny River in Pittsburgh, Pennsylvania. It carries Interstate 376 between the Fort Pitt Tunnel and Downtown Pittsburgh. Opened in June 1959 as a replacement for the Point Bridge, the Fort Pitt Bridge was the world's first computer-designed bowstring arch bridge: 00:02:43  and double-decked bowstring arch bridge. The bridge is known for its difficult lane changes, especially on the lower level, often requiring people to go from the extreme left lane across two lanes to the extreme right lane in only 300 feet. The upper level is more forgiving for some routes, but still requires a full span lane change in 300 feet to get from the south side entrance to the downtown exits.

Fort Pitt was a fort built by British forces between 1759 and 1761 during the French and Indian War at the confluence of the Monongahela and Allegheny rivers, where the Ohio River is formed in western Pennsylvania (modern day Pittsburgh). It was near (but not directly on) the site of Fort Duquesne, a French colonial fort built in 1754 as tensions increased between Great Britain and France in both Europe and North America. The French destroyed Fort Duquesne in 1758 when they retreated under British attack. British colonial protection of this area ultimately led to the development of Pittsburgh and Allegheny County, Pennsylvania by British-American colonists and immigrants.

The Allegheny River ( AL-ə-GAE-nee) is a 325 mi (523 km) long headwater stream of the Ohio River in western Pennsylvania and New York. The Allegheny River runs from its headwaters just below the middle of Pennsylvania's northern border northwesterly into New York then in a zigzag southwesterly across the border and through Western Pennsylvania to join the Monongahela River at the Forks of the Ohio on the "Point" of Point State Park in Downtown Pittsburgh, Pennsylvania. The Allegheny River is, by volume, the main headstream of both the Ohio and Mississippi Rivers. Historically, the Allegheny was considered to be the upper Ohio River by both Native Americans and European settlers. The shallow river has been made navigable upstream from Pittsburgh to East Brady by a series of locks and dams constructed in the early 20th century. A 24-mile long portion of the upper river in Warren and McKean counties of Pennsylvania and Cattaraugus County in New York is the Allegheny Reservoir, created by the erection of the Kinzua Dam in 1965 for flood control. The name of the river comes from one of a number of Delaware/Unami phrases which are homophones of the English name, with varying translations.
