Archaeologists have been studying megalithic tombs in northern Israel. They recently excavated one burial chamber with a mysterious example of rock art on its ceiling. This heap of stones and boulders is an ancient construction known as a dolmen.
Dolmens are found across the Levant, but this one is notable for two reasons: its size and its rock carvings. The Levant refers to an area encompassing modern-day Israel, Palestine, Lebanon, Jordan and Syria.
'Dark Ages' tomb
Archaeologists discovered the tomb while studying a field of dolmens near Shamir Heights in northern Israel.
The central chamber is capped by a huge 50-ton boulder, that likely would have required organized manpower to put in place.
