Entitled 'Purification,' this pig ready to be lit ablaze has been resting on its back on an artificial island in the Wisła River since 2012. No one really knows what it's about (it's art, man) aside from the clue in the title. Delighting joggers on their morning runs, this is also a good goal if you've renting a kayak and are in the middle of the Wisła with no idea what to do. Start the pig roast and invite us over, already.
