View through the "doughnut".

"Right on the beach, next to Brighton Pier, jutting out into the sea, is a large circular sculpture, a gift from the Mayor of Naples, officially called The Big Green Bagel but known locally as the "Seasick Doughnut". This unique piece is both loved and loathed by the residents of Brighton and has been the subject of many a heated debate in the past."

Not sure what the mayor of Naples got in return.
