Tholos de El Romeral in Antequera

You're standing at the Tholos de El Romeral, a little over two kilometres northeast of the town of Antequera. What you mostly see is a hill. But that hill was made by people. Underneath lies a tomb almost four thousand years old, built around 1800 BC, in the early Bronze Age. It's considered one of the most important examples of architecture from that period anywhere in southern Europe.
