The Marina Centre, which has been a long derided landmark on the seafront in Great Yarmouth, is being torn down to be replaced by a new swimming pool and leisure complex.
The brick building has been a fixture on the Golden Mile in the Norfolk beach resort since the 1980s but its uninspiring architecture hasn't always been popular.

Great Yarmouth Borough Council is spending £25.9 million on the new complex which will include a 25-metre pool, two water flumes and a one-hundred station gym and a four-court sports hall
The old Marina Centre was closed at the end of October 2019 and the council's demolition contractor is now clearing the site for redevelopment.
Construction is scheduled to start in summer 2020, with construction of the new complex complete in 2021.
"It's a once-in-a-generation investment which will be a major year-round boost to the flagship resort whilst supporting community health and well-being for everyone.

A six-lane 25m pool with disabled access and seating for 120 spectators
