Is Banksy setting up a new exhibition in Weston-super-Mare?

There is growing speculation elusive street artist Banksy is secretly creating a new pop-up exhibition at the old Tropicana in Weston-super-Mare.

A castle, a windmill and a metal horse are among works of art that have appeared at the site of the former outdoor pool and leisure facility, which closed in 2000.
