Lost City of Trellech: 'I bought a field not a home'

An archaeologist who bet his life savings on a hunch he had found a lost medieval city in Monmouthshire has said people thought he was "mad".

Stuart Wilson was convinced he had located the site of 13th Century Trellech - once Wales' largest city.

He invested more than £32,000 into a 4.6 acre (1.86-hectare) field at the edge of the modern-day village and started to dig.

Twelve years later, he believes he has revealed the footprint of a bustling iron boom town from the 1200s.
