A dolmen is a structure built by ancient humans which normally consisted two upright stones supporting a flattish capstone. There is a strong belief that Dolmens were used as tombs but we are not completely sure.
What is truly striking is that Dolmens are found in Europe, Asia, Middle East and Africa. The dolmens that were built so far apart geographically look similar. So did the habit of building dolmens start with one original group of early ancestors who spread it to all these other parts?
Just as I was researching this, I found that South Korea has the world’s largest concentration of dolmens.
My photographs of dolmens are from Tamil Nadu, India (near Kodaikanal)
