Exposition Park was located along the North Shore, in the City of Allegheny, across the Allegheny River from downtown Pittsburgh. It was built along the riverbank across from the Point, in approximately the same location as Three Rivers Stadium many years later. The stadium included a roofed wooden grandstand around the infield, and open bleacher sections extending to the right and left field corners. Total seating capacity was about 10,000 spectators. The seats faced the Allegheny River and the Point.

The stadium was built as an alternative to Recreation Park, which at the time was the largest sports venue in the Pittsburgh area. Recreation Park was the original home of the Pittsburgh Alleghenies Baseball Club, who in 1900 became the Pittsburgh Pirates. Exposition Park, opened in 1890, was originally constructed as the home field for the Pittsburgh Burghers Baseball Club of the Players League. The Burghers folded after one season and the Alleghenies moved into the new ballpark in 1891.

The first Major League baseball World Series was played at Exposition Park in 1903.

The Alleghenies, then the Pirates, remained at Exposition Park for nineteen years until 1909. In 1909 the team moved to Forbes Field in Oakland. Exposition Park was the hot spot in the National League at the turn of the century. The Pittsburgh Pirates won league championships in 1901, 1902 and 1903. In october, 1903, Exposition Park was the site of the first World Series, featuring the Pirates and the Boston Pilgrims. The final Pirates game at Exposition Park was played on June 24, 1909, before 5,545 spectators. The Pirates beat the Chicago Cubs, 8–1.

The Western University of Pennsylvania, who changed its name to the University of Pittsburgh in 1909, also called Exposition Park home. From 1890 through 1903, the University played some games there, and in 1904 began playing all home games at the North Shore venue. The 1904 W.U.P. team posted a 10–0 record in which they outscored opponents 407-5. Like the Pirates, the Panthers moved to Forbes Field for the 1909 season.

Exposition Park and the north shore are partially submerged during a 1913 flood.

Exposition Park's location near the banks of the Allegheny River was a problem when the river flooded, which before flood controls were in place was quite often. Flooding sometimes covered the outfield with inches of standing water, forcing ground rules that gave any ball hit into the outfield an automatic single. During a July 4, 1902 doubleheader against Brooklyn, a flood caused the water level to rise thigh high in center and right fields, and head deep in center field. Players occasionally caught a ball and dove under the water. The Pirates won both games.

The sports venue was used until approximately 1915, then was razed. Today, the parking lot between the Fort Duquesne Bridge and Heinz Field is the location of the old stadium.
