Spartan Stadium, formerly College Field, Macklin Field and Macklin Stadium, opened in 1923 in East Lansing, Michigan. It is the home field of the Michigan State University Spartans. After the addition of luxury boxes and club seating in 2004-2005, the capacity of the stadium grew from 72,027 to 75,005, though it has frequently held more than 80,000 fans, making it the Big Ten's fifth largest stadium. Spartan Stadium has been recognized as the 8th most scenic college football venue in the country. Home to one of the top turfgrass research programs in the nation, Michigan State installed a natural grass field in 2002, replacing the artificial turf. The Spartans have ranked among the NCAA's top 20 in attendance each of the last 47 years.
