US Stonehenge

Mystery Hill (the Mystery Hill) has been called the Stonehenge of America.
It is an amalgamation of stone buildings, wells and underground chambers, occupying about 48,000 m2 in Salem, New Hampshire. In the center erected a slab weighing almost 5 t is called the Altar of Sacrifices, because it is believed that on it were victimized victims. They surround the set of stone columns that seem to relate to the seasons of the year. The antiquity of charcoal found with old utensils, scientifically proven, goes back to the year 2000 before Christ
