Nanteos Mansion, near Aberystwyth, England, was built in the 18th Century, has been linked to the Holy Grail and sports many ghost stories.
British police raided an English country pub this week in search of a stolen wooden relic believed by some to be the Holy Grail - a cup from which, according to the Bible, Jesus is said to have drunk at his final meal before crucifixion.
The Grail has captivated religious experts for centuries, spawning myriad theories about its location and inspiring numerous fictional accounts from the Middle Ages onwards.
Cwpan Nanteos: The Healing Cup. Originally in Strata Florida Abgey, and believed to be made from the wood of the Holy Cross.
The object of the police search, which was unsuccessful, was a frail wooden bowl known as the Nanteos Cup
that has been attributed with healing powers since the 19th century, attracting pilgrims and others who believe it may be the Holy Grail itself.
After receiving a tip-off, a team of eight officers and a police dog arrived on Sunday morning at the Crown Inn, a village pub in
the rural English county of Herefordshire.
"They turned the place upside down. They came with fibre optic cameras to look in all the corners and nooks and crannies, and under the floorboards ... they were clearly serious about it," the pub's landlady, Di Franklyn, said.
Police said the relic, a dark wooden cup kept inside a blue velvet bag, had been stolen from a house in the area about a month ago. Photographs available online show a bowl-shaped vessel with around half its side missing.
"We get a few rogues and scallywags in the pub, but no one who's quite on the level of stealing a priceless ancient artefact," Franklyn said.
