The Freitas Memorial Gymnasium is a hub of student activity. In addition to a number of visual arts classrooms, the building houses male and female locker rooms, male and female team rooms and coaches’ meeting room. It also holds The Wildcat Den, which serves food during games, the Athletic Hall of Fame, and the Athletic Department offices. Its most recent remodel, which began in July of 1983 and was completed in February of 1984, doubled its seating capacity to nearly 1,000 people. New bleachers that feature the school’s mascot “CATS” spelled out in shadow were added in 1997. The gym is utilized by 14 Marin Catholic teams for training and competition as well as by multiple outside community programs.
