More than 20 landmark buildings, homeowners and businesses were honored Thursday for preserving historic Chicago -- and among the projects recognized was an expansion of Wrigley Field's bleachers. The Commission on Chicago Landmarks presented the Chicago Landmark Awards for Preservation Excellence during a ceremony at the LaSalle Bank Theater. The theater, formerly called the Shubert, recently completed a $40 million, yearlong restoration and was among the 21 honorees. Wrigley Field, home of the Cubs, was built in 1914 and is the second-oldest major league ballpark. The boomerang-shaped bleachers were added in 1937. The Wrigley alterations were completed by opening day this spring and increased bleacher capacity by almost 1,800 seats.
