I wonder if you are on some kind of archaeological site
I live on a rural estate that appears in the records as far back as the 11th century. It has a very rich history. It was the property of Norman Knights since soon after the Conquest. I know a bit of the history of most of the families that owned it over the centuries. I have written it up for the current landowner.
There was a medieval village here but due to it's proximity to the Scottish border it was attacked many times. It is likely that it also fell victim to the plague.
One interesting highlight is that The earl of Bothwell hid here for a few nights in 1563 when he was on the run from being imprisoned in Edinburgh Castle. He was betrayed and recaptured here in the middle of the night and taken to the Tower of London. He later went on to murder Lord Darnley the husband of Mary Queen of Scots and to take Mary as his wife. He vowed revenge on the owner of the estate who had betrayed him.
As well as coins I find a lot of everyday objects.
