Welsh leaders before the Roman invasion ruled from hillforts whose stone ruins still overlook every part of the country, an archaeologist has said.
Aberystwyth-based Toby Driver said there were "big stories" still to be told about Wales' 764 Iron Age hillforts.
One of the largest, Garn Goch, looms over Bethlehem in Carmarthenshire.
Villagers said they "respect" the sprawling monument, but know little about the people who built it.
"People get very excited about the pyramids of Egypt and monuments around the world," Mr Driver said.
"We should be getting excited about this incredible hillfort heritage we have in Wales."
His new book, Hillforts of Iron Age Wales, includes illustrations showing what these "vibrant hill top villages" would have looked like 2,500 years ago.
