Time Team was a long running, and popular archaeology TV show. The team were invited in to undertake exploratory investigation and excavation at sites across the UK (I think they even popped over the pond to the New World for one excavation). They then had 3 days to try and make sense of the site. Archaeology, historical survey, landscape surveyors, historical researchers, experimental archaeologists, re-enactors, and a graphic artist all attempting to make the site come to life. There were even live broadcast versions. They made some significant finds including an unknown extensive Roman villa complex. The presenter was Sir Tony Robinson (who played Baldrick in the various Black Adder series), the archaeologists involved in the original TV show were top notch. A number of them have become TV celebrities in their own right, for example Prof Alice Roberts.
Time Team had/has a good reputation for what it is; a number of 'copies' of the format have surfaced over the years.
When it was cancelled by Channel 4 it was greatly missed. But has since returned via Patreon and YouTube. Many of the original academics are still connected to the show. I've only seen short clips from the 'new' incarnation which looks good, not quite as good as the original TV version. But that could be the nostalgia effect.

Of the original programmes there were a couple that looked at ECW sieges, lost castles, a Napoleonic prisoner of war camp, and more Roman settlements than you could shake a stick at.
