The old town was formerly a fishing harbour which in 1301 was recorded to have 150 homesteads with 800 inhabitants. A mediaeval wooden lighthouse, known locally as a foïer, was built on a dune and lit by charcoal and faggots but this burned down several times. On one occasion at least it was as a result of the continuous conflict between the English and the French in the Hundred Years War. The chronicler Enguerrand de Monstrelet mentions that during 1414 the English garrison in Calais raided south and burned the town. Eventually the lighthouse was replaced by a stone tower at the side of which a chapel was built in the 15th century, but this did not save it from further mishap. During the second siege of Montreuil in 1544, the English advanced from the south and burned 200 houses, the church and the mill as they passed through Berck. What was left of the place was then burned by the French on their way to relieve the siege.
The world premiere of the film Exit Through the Gift Shop occurred at the Sundance Film Festival in Park City, Utah, on 24 January. He created 10 street artworks around Park City and Salt Lake City to tie in with the screening. In February, The Whitehouse public house in Liverpool, England, was sold for £114,000 at auction. The side of the building has an image of a giant rat by Banksy.
A pop-up boutique of about 25 spray-art canvases appeared on Fifth Avenue near Central Park on 12 October. Tourists were able to buy Banksy art for just $60 each. In a note posted to his website, the artist wrote: "Please note this was a one-off. The stall will not be there again." The BBC estimated that the street-stall art pieces could be worth as much as $31,000. The booth was manned by an unknown elderly man who went about four hours before making a sale, yawning and eating lunch as people strolled by without a second glance at the work. Banksy chronicled the surprise sale in a video posted to their website noting, "Yesterday I set up a stall in the park selling 100% authentic original signed Banksy canvases. For $60 each." Two of the canvasses sold at a July 2014 auction for $214,000.
