W.B. Mason Stadium is home to Stonehill field hockey, football, lacrosse, and track & field, and is one of the premier athletic facilities in the Northeast-10 Conference.
Formally dedicated on September 10, 2005, the 2,400-seat stadium is the College's newest athletic facility and features artificial turf, a 400-meter eight-lane track, specialty areas for track and field events, and lighting for evening events. The playing field, Timothy J. Coughlin Memorial Field, was named in memory of Stonehill Class of 1980 football standout Tim Coughlin.
W.B. Mason president and CEO Leo Meehan, a Stonehill trustee and alumnus, announced prior to development of the facility that the company and its alumni employees would contribute $1.5 million of the $4 million cost of the project.
