The Gymnasium is at the centre of Southwell School's sport facilities, close to fields, the astro turf and the swimming pool.  Included in the gym are changing facilities, toilets and showers for sports teams.

During the winter months the gymnasium is a invaluable for indoor training.  Think Beep tests, Gymnastics, Dodgeball, and Basketball games and you get the idea of the energy and excitement this area of the school generates.
