Thousands of people had the chance to explore the new Westminster Lodge Leisure Centre at its launch weekend.
More than 8,000 people visited the centre on Saturday to check out the new facilities.
Claire James, PR manager for the centre, described the event as "extremely successful".
She said: "It was incredibly busy.
"It was above and beyond expectations.
"The corridors were absolutely rammed from the time we opened until we closed.
"I never saw a time when the pool wasn’t packed with people."
A host of sporting celebrities, including Saracens players and members of Team GB and Paralympics GB, attended the event.
Paralympic rifle shooter Georgina Callingham, gymnast Max Whitlock and open water swimmer Kerry-Anne Payne were just some of the special guests.
