The Tumulus of St. Michel is a megalithic grave mound found in Carnac, France, dating back to around 4500 BCE. At 125m(410ft) long, 60m (196.85ft) wide, and 10m (32.8ft) high, the tumulus is the largest burial mound in continental Europe. The mound was excavated in 1862 and researchers found a central vault containing fairly prestigious funerary furniture such as axes, pearls, flint tools, and sillimanite – all of these objects are now located at the Carnac and Vannes Polymathique museums. It was declared a Monument historique (French national heritage site) in 1889. Today, the St. Michel chapel is located on the tumulus’ summit.
