EXETER’S UNDERGROUND PASSAGES
Built in the 14th century the crude, narrow tunnels run under a large portion of the city of Exeter. When they were constructed, the shafts actually ran past the city limits under the protective outer wall to natural springs which would provide the citizens behind the wall with clean drinking water, a precious commodity in medieval times. The passages are short and tight which made work in the tunnels a cramped and uncomfortable business. When civil war did finally come to the city, many of the tunnels and chambers were bricked up to prevent them being used as a military backdoor. The water works were reopened after the fighting stopped and the aging tunnels were continually improved upon over the centuries, eventually incorporating England’s first use of cast iron piping.
