The Margate Shell Grotto is an ornate subterranean passageway in Margate, Kent, England, adorned with intricate mosaics made entirely of seashells. Discovered in 1835, the grotto's origins and purpose remain a mystery, sparking much speculation and curiosity. 

How there is no record or idea of how this place came about is pretty wild. And like most wonders of the world we have no clue about, the craftsmanship of this place, and just pure size and scale of it is mindblowing. 

Keep the suggestions coming. Keep them classy. No butt stuff.
