In 1835, a laborer in Kent, England, was doing his usual field work. What wasn’t so usual was when he struck the soil with his spade and it just disappeared into the Earth. Apparently, he was standing on something hollow, but from the surface, he could see nothing.
Word spread, and a local schoolteacher soon volunteered his young son, Joshua, to be lowered into the hole with a candle. If you think dipping your child into a mysterious cavern in the Earth seems a bit, well, unsafe, we do, too. Luckily, Joshua was fine, and what he saw underground was a breathtaking mystery.
When Joshua was pulled out, he described rooms filled with hundreds of thousands of carefully arranged shells.
Needless to say, the adults were a bit skeptical, but when the hole was widened and they saw if for themselves, they were stunned. There was a passage, a rotunda, and an altar chamber, and the whole thing was covered in a mosaic of shells.
Joshua’s father, the schoolteacher, immediately thought of the financial benefit that this place might have. He quickly bought up the land and began renovating the grotto, making it suitable for visitors. Two years later, in 1837, the Margate Shell Grotto opened to the public for the first time. And he was right; it did catch on with the public, and it’s still open and enjoying visitors today. Today, it’s also got a museum, gift shop, and cafe.
But there’s still a major question hanging in the air: who built this, and why?
With all these shells so carefully arranged, it’s clear that someone spent a lot of time — and money — on this creation. The shells are arranged in sun and star shapes, and vaulted ceilings and altar-like spaces lead some to believe it once had religious significance. Yet no one knows for sure, and no one is even sure how old the structure is.
Theories about its origin place it as being built as long as 3,000 years ago.
Other theories also run the gamut between ordinary and totally out there. Some think it was created as an aristocrat’s folly sometime in the 1700s. Others think it might have been used as an astrological calendar, or that it’s connected with the Freemasons or the Knights Templar. Still, others maintain it is connected to a mysterious Mexican culture that lived some 12,000 years ago.
Shell grottoes were actually quite popular in Europe in the 1700s among the wealthy.
There’s only one catch: the grotto’s location was on farmland, and that land has never been part of a large estate, where follies would have been built. Even in 1835, there was no record of its construction, which would have been a major undertaking. People have been so stumped by this that in the 1930s, people held seances in the hopes of contacting the spirits of whoever built it.
Visitors from the 1930s left their mark on some scallop shells in the grotto.
The shells in the grotto, which include scallops, whelks, mussels, cockles, limpets, and oysters, can all be found locally. Only the flat winkle shells had to be brought in from elsewhere.
The arrangement of the shells must have taken countless hours of painstaking work.
In all, there are over 2,000 square feet of shell mosaic in the grotto.
Many of the shells in the grotto have faded over time and lost their luster through water damage. This recreation shows what they might have looked like at the time the grotto was built. It would have been full of dazzling color.

To determine the age of the shells, they could be carbon dated. However, on the Shell Grotto’s FAQ page, it’s stated that this process is very expensive, and other conservation issues are currently prioritized. Perhaps one day, we’ll at least know when this was built. For now, our imaginations can run wild with all the possibilities of the Shell Grotto’s mysterious past. Was it a smuggler’s hideout? A secret temple? An underground party room? The life’s work of a madman? Whatever it was, someone obviously cared about it enough to decorate it like this.
