Beach at Pourville was stolen on 19 September 2000 from the National Museum in the western city of Poznan. The painting, worth from 3 to 7 million dollars, located in the Monet exhibition room, was not properly protected – there were no CCTV cameras in the room and the paintings were not in glass cases. The thief cut the painting out of the frame and replaced it with a forgery.
