Councillor Carl Quartermain, cabinet member for highways and transport, said it had been sad to see the seals “looking so poorly”.
He said: “It’s going to be glorious to see them back to full splendour.
“I’d like to mention my colleague, councillor Lynne Rynn, who has pushed for the seals to be returned and I’d also like to thank everyone involved, including those with the original vision for the sculptures back in 2011.”
A film is being made by Neil Bates, former Regent Cinema manager, called Four Seals.
