Forbes Field was a baseball park in the Oakland neighborhood of Pittsburgh, Pennsylvania, from 1909 to June 28, 1970. It was the third home of the Pittsburgh Pirates and the first home of the Pittsburgh Steelers.The stadium was named after British general John Forbes, who fought in the French and Indian War, and named the city in 1758.
The US $1 million ($26.3 million today) project was initiated by Pittsburgh Pirates’ owner Barney Dreyfuss, with the goal of replacing his franchise’s then-current home, Exposition Park. The stadium was made of concrete and steel (one of the first of its kind) in order to increase its lifespan. The Pirates opened Forbes Field on June 30, 1909 against the Chicago Cubs, and would play the final game that was also against the Cubs on June 28, 1970.
