Why it's Wildland
4.4Beneath an unassuming Margate street, a winding chalk passage opens into rooms covered with intricate shell mosaics. The grotto was discovered in the 19th century, but its maker, purpose and date remain unknown.
A subterranean shell mosaic on this scale is a genuine surprise beneath a Margate back street. Its twisting passages and unresolved origins make it a distinctive place to explore, even though the visit is brief and entirely underground.

Verified history
The grotto was discovered beneath Belle Vue Cottage in the 19th century. The official account says the earliest reference it has found is a Kentish Gazette notice dated 22 May 1838, announcing the attraction’s forthcoming opening. Frances Newlove later gave a different recollection of how the underground space was found, so the discovery story is not entirely settled. The grotto’s date, makers and original purpose remain unknown.
Folklore & legend
The grotto has inspired theories that it was a place of worship, a secret meeting place, a smuggler’s cave or an extravagant folly. These are competing interpretations, not verified explanations; the official site says its origins remain unknown.
Hidden details
Shells from different shores — The official account says most of the shells are native to the British Isles, with some exotic examples including queen conches from the Caribbean. Look carefully for changes in shell type and pattern.
Repairs leave their own clues — The official site reports that mortar samples examined during a 2009 condition survey differed from one another, possibly reflecting successive repairs. It also points out small slate patches in the grotto.
