Home to the Guilford's football, men's soccer, women's soccer, men's lacrosse and women's lacrosse teams; Armfield Athletic Center is a 2,200-seat stadium located on the southeast corner of the campus. The stadium has both aluminum bleacher seating and stadium seating. The stadium is equipped with a state-of-the-art scoreboard, sound system, and lights for night games. The playing surface was expanded and covered with Field Turf in the summer of 2009.
The Armfield Athletic Center was originally constructed with funds from the Armfield family and friends and dedicated in honor of William J. Armfield Jr. and in memory of Britt M. Armfield and William J. Armfield III. The elder William Armfield, who died in 1968, played on the college's first football team in the late 1800s. Both William Armfields were Guilford alumni.
In 2006, Armfield Athletic Center received the first phase of an estimated $2.5 million renovation project. The first phase included a new press box, stadium seating, refurbished bleacher seating, a multi-function scoreboard and exterior fence. The Armfield Athletic Center's game field was renamed in honor of Dr. Herbert T. Appenzeller, who worked with the Armfield family 45 years ago to build the athletic complex. In his nearly 40 years at Guilford, Appenzeller’s work as a professor and administrator produced many scholars, athletes and leaders in their fields. In 2007, the field received new visitor bleacher seating and field lights. October 2008 saw more exterior improvements with a new entry plaza and gate at the north end of the stadium. The summer of 2009 saw a 106,000 square feet Field Turf playing surface installed. Subsequent phases are slated to include additional seating.
