College Station exists because of Texas A&M University, and Aggie traditions shape nearly every part of the city. Kyle Field, one of the largest college football stadiums in the country, fills with maroon crowds on game days. The George Bush Presidential Library and Museum, on the university campus, presents the life and presidency of George H.W. Bush with exhibits and a replica Oval Office. Century Square, a mixed use district near campus, offers restaurants, shops, and gathering space, and Research Park supports university research and innovation.
