Great Big Story took a short but detailed visual trip into the beautifully decorated subterranean Shell Grotto that exists below the seaside town of Margate, Kent, U.K. Its origin and purpose has been a complete mystery since it was discovered in 1835.
Less than six feet beneath a residential neighborhood in the English seaside town of Margate lies a mysterious underground cavern. Nicknamed Shell Grotto, the subterranean passages wind for 70 feet and are adorned by millions of seashells. Who built the cavern and for what purpose remain a mystery.
