Redland Field 1930, whose name was a reference to the Reds' name and color. It was one of many classic steel and concrete ballparks constructed during the first ballpark boom era of 1909–1923. Chicago's Wrigley Field and Boston's Fenway Park were also built during this era and remain in use today. Although occupying the site since 1884, the Reds dated their ballpark from the permanent structure opened in 1912. Throughout its history, Redland/Crosley Field was usually among the smallest parks in the major leagues. It accommodated 25,000 fans in 1912; even at its peak, it barely exceeded 30,000 seats, excluding temporary seating areas created for opening day and World Series games. Contributing to this was the fact that there were no bleachers in left or center fields; all outfield seating (about 4,500 seats), were in the semi-trapezoid-shaped right field stands that came to be known as the "Sun Deck" (or, in the case of night games, the "Moon Deck").
