This week's Offbeat Traveler is from Times reader Adam Allegro. During a trip to southern Sweden in early September, Allegro visited Ale's Stones, a megalith monument in the country's Scania province. The monument, which measures over 219 feet long and 62 feet wide, is composed of 59 stones arranged in the shape of a ship. Each stone weighs between 1,100 and 4,000 pounds. The origin of Ale's Stones is unknown, but archeologists believe it may have served as a calendar or a memorial to shipwreck victims. Researchers estimate that the monument is at least 1,400 years old. Allegro is an avid photographer. He shares photos from his travels on his blog "Catch the Jiffy."
