The Welsh Society or the Gym Gym as it is called is central to the life of Welsh-medium University students in Swansea. It's a great opportunity to make new friends. The Welsh Society meets regularly organising a host of social activities through the medium of Welsh including rugby trips, gigs, and crawls, Inter Eisteddfodau and much more. The Welsh Society works closely with the Coleg Cymraeg Swansea Branch and Tawe Rugby Club.
In 2016-17 the Gym Gym was one of four Societies to receive 'Gold' within the Swansea University Student Union system. The society is now a 'Golden Society'.
