When archaeologists working on the route of HS2 began excavating a stretch of pasture in Warwickshire, they were not expecting to uncover what one of them calls “the highlight of our careers”. Their excavations revealed the monumental stone bases of two towers from a late medieval fortified gatehouse, the existence of which had been completely lost to history.
While that find was remarkable in itself, the ruins were even more significant than they first appeared – and might even rewrite the history of the English civil war.
