RESEARCHER, presenter and internationally published author Robin Heath will announce a major new discovery about Stonehenge at the Small World Theatre in Cardigan on Sunday, June 22.

Despite the best efforts of archaeologists over four centuries, the iconic monument in Wiltshire has so far eluded every attempt to explain the big questions: What was its purpose and why was it built?

Robin Heath has been attempting to solve them for the best part of 30 years and claims the answer is to be found in the landscape of north Pembrokeshire, near Newport.

Last summer he discovered a previously unknown megalithic complex, a Proto Stonehenge, forging a second link between the Preseli region and Stonehenge.

This discovery, duly surveyed with modern theodolites, GPS and satellite imagery, reveals that Stonehenge was the end result of a long project undertaken over many centuries, with a goal to develop a Neolithic technology capable of accurately measuring and recording time and space. Once understood, it allows us to lift the capabilities of Neolithic culture to a new level.

In an event filled with photos, models, excitement and humour, Mr Heath will take his audience on a timeline from 3150 BC to the present, explaining why the Preseli region of west Wales was so important to the builders of Stonehenge.

He hopes the event will bring a new era in our understanding of Stonehenge’s origins – why it is located where it is and its prime function. The presentation will be followed by a lively question and answer session.

The event starts at 2pm and tickets cost £4. They can be booked in advance by visiting www.smallworld.org.uk.

Each member of the audience will receive a limited edition, fully illustrated and signed copy of Mr Heath's report detailing the locations, the history and the recent context of research into Stonehenge.
