Poet Alexander Pope lived in Twickenham during the 18th century. The villa he lived in, which was built on the banks of the Thames in 1720, was demolished during the early 19th century, but one fascinating relic still remains. A hidden, subterranean bunker, the restoration of which continues to this day.
It is now owned by a local school, but special public openings do take place. Check out the Pope's Grotto Preservation Trust website to find out when you can next descend down into this west London wonder.
To find out more visit the Pope's Grotto Preservation Trust website, including information on the history, restoration and upcoming opening days of the grotto. Pre-booking is absolutely necessary.
