Just watched those Moss, thank you for putting them here.
I felt I learnt some facts by watching them. I didn't know for instance the wooden track known now as the Sweet Track was only used for a relatively short time (nine years).
The Glastonbury Lake Village - preserved under water logged peat for 2,000 years - was very watery indeed.
It seems people moved on - you can't help wondering why they lived there at all, although as the most recent film in the time line pointed out, the water gave them protection.
