This was a Time Team Special in 2005 [Series 18, Episode 138], unfortunately named the "King of Bling". The location was given as Prittlewell, Essex [on the outskirts of Southend]. For non-Brits, Time Team has been a very long-running series on British TV, popularising field archeology to a very wide audience. It took a 'quick hit' approach following-up local suggestions to do a single week's digging with good resources. It reported the week's progress in a single, compact and well-structured broadcast. Much loved, it is now in hiatus, if not gone forever. Why it was not mentioned in connection with this 'discovery' is hard to say...
