20m pool

The 20m pool at St Mary's Hospital 

Whether you simply want a relaxing swim at the end of a hard day or whether you're training for a competitive event, 20m swimming pool, set in bright and modern surroundings, provides an ideal swimming environment.   

St Mary's Pool update: Friday 21 September 2018

The swimming pool at St Mary’s Campus, which was due to close in July, has remained open over the summer and will now continue to operate for all of this academic year. This decision follows representations from staff and other users of the pool who have said how much they value the pool.

Refurbishment works are still required and the College is exploring options for covering and offsetting some of the costs.

The decision to keep the pool open will be reviewed on an annual basis and users will be updated of any decision.

For now the current opening hours will remain in place. Sport Imperial will meet with users from the pool to discuss whether adaptations can be made to the opening hours without increasing costs.
