What Our Investigators Say
“A weekend of insanely fun and intense gaming that you can't easily replicate at home or at a convention.”
— Rick Meints, President of Chaosium“Cthulhu in a Castle is a highly immersive and thoroughly enjoyable luxury TTRPG experience. They have thought of nearly everything, from GMs, Discord, character creation, and on-site assistance and tours of the beautiful venue to catering and much more! I would recommend anyone who can squeeze this into their schedule to do so; I had an absolute blast!”
— Austin“Our GM (Keeper) was stellar, both entertaining and deft at managing the pacing and engagement in the game. It was fun that most players and the Keeper did a bit of cosplay too. The event really had this 60-year-old man feel like he was reliving the glory days of teenage RPG games with his friends.”

Your Next Scenario Deserves a Castle!
Glencairn — The Castle
Glencairn is the real thing: a stone castle-estate of great halls, medieval arches, stained glass, and genuine artifacts along the walls. Follow the clues beneath vaulted ceilings while shadows gather along the stone walls. This is the kind of setting where an investigation stops feeling imaginary.
“The setting was truly inspiring for the gameplay.”
— Scott
Cairnwood — The Palace
Where Glencairn is stone and steel, Cairnwood is candlelight and gold. A Gilded Age mansion of opulent rooms and sweeping staircases, lit low against the evening — the perfect setting for whispered suspicions, forbidden discoveries, and an investigation that grows darker with every hour.
“It is an amazing venue. Big enough that you get to meet people from all over, but small enough that you don't get lost or feel overwhelmed.“
— Michael
Getting there is the last easy part…
The majestic historic district of Bryn Athyn hosts many of our events. This world of genuine Gothic revival and Gilded Age architecture is just 40 minutes north of Philadelphia’s airport. We offer room-inclusive and commuter (no room) ticket options.
