Ales Stenar aka Ale's Stones in Sweden.
A little fishing village in Sweden is used to getting a bit of attention for its’ unusual set of monolithic stones that were placed in the outline of a ship on it’s beautiful, bright green coast 1,ooo years ago. Some recent investigations on the other-hand, have discovered the stones may actually date back quite a bit older than originally thought, from 1,000 years old to 2,500 years old.

Ancient Scandinavians dragged 59 boulders to a seaside cliff near what is now the Swedish fishing village of Kåseberga. They carefully arranged the massive stones — each weighing up to 4,000 pounds (1,800 kilograms) — in the outline of a 220-foot-long (67-meter) ship overlooking the Baltic Sea. Archaeologists generally agree this megalithic structure, known as Ales Stenar (“Ale’s Stones”), was assembled about 1,000 years ago, near the end of the Iron Age, as a burial monument. But a team of researchers now argues it’s really 2,500 years old, dating from the Scandinavian Bronze Age, and was built as an astronomical calendar with the same underlying geometry as England’s Stonehenge.
