Acton Castle, Grade II* listed castle in Perranuthnoe, England
The castle features a central tower with two added wings, constructed using brick faced with local Cornish granite and topped by embattled parapets.
John Stackhouse commissioned the castle in 1773, naming it after his wife Susanna Acton, and used it as a base for his marine biology research.
The castle grounds contain remnants of large tanks where John Stackhouse conducted his studies of seaweed species for his publication Nereis Britannica.
The castle transformed from a private residence to a country hotel and now contains luxury apartments overlooking St Michael's Mount in Mount's Bay.
John Carter, a tenant known as the King of Prussia, used the castle as a smugglers' hideout, with local stories mentioning secret tunnels to Stackhouse Cove.
