First we walked into a marquee and she showed us how small ditches around the edges of Celtic houses fill up with silt over time and if you dig down to their level you can see where the ditches were by seeing the differently coloured soil.
Then we went to the dig sites. Firstly, there was a Celtic house and a Roman road. The gutters at each side of the road had filled up in the same way as the Celtic ditches. We could work out they were from different periods as the Roman road was built smack on top of the Celtic house.
Then we walked through the horrid mucky grounds dotted with last seasons potatoes to another dig where they'd found the site of a Victorian rubbish dump. There was lots and lots of Victorian rubbish piled on top of each other. We could see it under the ground through the archaeologists trench. One of the walls was practically made up of rubbish.
It was interesting and I learned a lot!
