RAVENSBURG, Germany (AP) -- Some 15,000 enthusiasts have assembled the world's largest jigsaw puzzle in the southern German town of Ravensburg, Europe's biggest puzzle maker said.

The puzzle nearly covered the entire town square at Ravensburger.

Puzzle maker Ravensburger AG said 1,141,800 pieces were put together in only five hours on Sunday forming a nearly 600-square meter (6,500-square foot) puzzle that nearly covered the town square.

"We really like puzzling," Ravensburg resident Sonja Haussner said at the event.

A notary has submitted the result to the Guinness Book of World Records. Organizers say it is significantly bigger than the current record -- a 212,000-piece puzzle put together in Singapore in 2002.
