About

A Nightmare from overseas has arrived...London, You're Next!

Europe's award-winning immersive horror experience has crossed the Irish Sea. For seventeen years The Nightmare Realm has been creating immersive horror unlike anything else in Europe.

Now, for the first time, the gates open in London. Inside, you'll explore a living world where vampires, forgotten patients and twisted souls already have stories unfolding around you.

The Nightmare doesn't begin when you arrive. It was waiting long before you got here. London, you've been warned.
