The UK is blessed with hundreds of beautiful seaside towns. Each has something different to offer, and some even hold secrets not many are aware of. One of the most popular seaside destinations is Margate on the Kent coast. Not only does it have seaside charm and beautiful beaches, but it is also home to a jaw-dropping underground cave made entirely of shells.
Known as the Shell Grotto, it was discovered by chance in 1835 and remains one of the country’s greatest mysteries. The 70ft (21-metre) tunnel is covered in 4.6 million shells forming intricate mosaics of gods, goddesses, trees of life, and swirling patterns. Nobody knows who built it or why.
Some believe it was a place of worship, others think it was a secret meeting spot, and some say it’s just an extravagant Regency folly.
But no records exist, and nothing was found to link it to any known estate or historical building.
According to the Grotto’s official website, the first paying visitors came in 1838, just three years after it was uncovered during building work. Ever since, debates have raged about its origins.
Experts explained that the shells used to create the mosaic include common British varieties such as cockles, mussels, whelks and oysters, but there are also a few exotic ones like queen conches from the Caribbean, found in the corners of the Altar Room, Visit Thanet says.
Despite the mystery, one thing is certain: the Grotto is a unique work of art.
It’s not the easiest place to visit. The entrance is located on a steep road, with steps leading down into the cave and low lighting throughout the tunnels.
The terrain is uneven, sloped and narrow in places, meaning it’s unfortunately not accessible to wheelchair users.
Tickets are priced at £4.50 for adults, £4 for concessions, £2 for children aged 4-16, and free for those under four. A family ticket (2 adults and up to 2 children) costs £10.
The Shell Grotto is Grade I listed and was once at risk of crumbling, but it was removed from the Buildings at Risk register in 2012 thanks to conservation work supported by Historic England and the Friends of the Shell Grotto trust.
For those heading to Margate, the Grotto is just one of many reasons to visit.
The seaside town is known for its sandy beaches, fresh seafood, retro shops and artsy feel.
