Berck, France

Its difficult to imagine anything more depressing than a seaside resort on a freezing cold, miserable spring afternoon. But at least it had a lighthouse. Original towers had been destroyed by the retreating Germans in 1944, but this 1951 effort appears on all the merchandise in the town's souvenir shops.
To find it, head to the front, turn left and drive as far as you can. Shortly after the road bends left, you will see it to your right at the end of a school car park.
