Based on a physical examination of the Grotto, reviewing accurate plans, the published literature and comparing it with other underground structures it is the writer’s personal opinion that a small mediaeval denehole was reworked and extended at some time after the original mining had ceased. The skill required to cut the passages to a relatively complex predetermined plan would indicate that the date of the
reworking could be from the 17th century onward although an 18th century date would seem more likely. It is probable that the shell
decoration was undertaken at the same time or very shortly afterwards. The Margate Shell Grotto http://www.kentarchaeology.ac/authors/023.pdf1804 wurde in der Nähe der Margate Shell Grotto schon eine andere ähnliche bei Umbauarbeiten gefunden, sie war bekannt als Mrs Hills Grotto House und war wohl eine private katholische Kapelle der Vorbesitzer, mit der Zeit wurden die Muschelpanele entfernt und zum Keller umgebaut.
The other grotto was found during building work on the west side of Margate High Street on the premises of a Mr Oldfield who held a 25year lease on the house which he converted into a boarding school. [...] The site was incorporated into the cellars of the house which became known as Mrs Hill’s Grotto House, Mrs Hill being the Landlord and owner of Grotto House and the adjacent Garden House.
At some time after its discovery the shell panels were removed and the site became a simple barrel vaulted cellar extension. http://www.kentarchaeology.ac/authors/023.pdf
