The Hellfire Club

Montpelier Hill, Dublin

A ruined hunting lodge where, legend says, the Devil came to play cards.

The ruined lodge on Montpelier Hill was built around 1725, partly from stones taken from a prehistoric cairn. Later, the rakish members of the Irish Hellfire Club were said to meet here for drinking and devil worship.

The Ledger of Lost Artifacts and Civilizations

Not every mystery needs a lost continent. This book investigates fifty-nine real and often overlooked puzzles from the ancient and modern world: a temple older than farming itself, astonishing structures, out-of-place artifacts, and technologies lost to time. Each case is weighed honestly, with a clear ledger of the case for and against, so you can make up your own mind. Some cases collapse under scrutiny. Others remain genuinely unexplained. All of them are stranger than Atlantis.
