Flip side of that, when you watch time team and they dig down a few feet to find the floor of a building that was there 100's of years ago why do they have to dig down ? why are these things buried ? did folk years ago dig a big hole and build in the hole or is it the soil that has built up over the years and buried these old buildings ?Does the iron post that was sunk into one of the fens when it was drained and now sticks 10 ft out of the ground not tell a story?
does that not tell a story ?
