What year did the National Football League's Lambeau Field open?

Lambeau field an outdoor athletic stadium in Green Bay, Wisconsin, United States. The home field of the Green Bay Packers of the National Football League (NFL), opened in 1957 as City Stadium, replacing the original City Stadium at Green Bay East High School as the Packers home field. Informally known as New City Stadium for its first eight seasons, it was renamed in August 1965 in memory of Packers founder, player, and long-time head coach, Curly Lambeau, who had died two months earlier.

The stadium's street address has been 1265 Lombardi Avenue since August 1968, when Highland Avenue was renamed in honor of former head coach Vince Lombardi. It sits on a block bounded by Lombardi Avenue (north); Oneida Street (east); Stadium Drive and Valley View Road (south); and Ridge Road (west). The playing field at the stadium has a conventional north–south alignment, at an elevation of 640 feet (195 m) above sea level.

The stadium completed its latest renovation in the summer of 2013 with the addition of 7,000 seats high in the south end zone. About 5,400 of the new seating is general, while the remaining 1,600 seats are club or terrace suite seating.With a capacity of 81,441, Lambeau Field is the fifth-largest stadium in the NFL with standing room, but is third in normal capacity. It is now the largest venue in the State of Wisconsin, edging out Camp Randall Stadium (80,321) at the University of Wisconsin.
