⌖ The Sealed Room Co. Clerkenwell · London

Five rooms. One war.

The Sealed Room Co.

Five escape rooms in a converted print works in Clerkenwell, each one set somewhere in the Second World War or its long shadow. We open Wednesday through Sunday, two slots an evening. Bring three to six players and an appetite for ciphers.

Built by ex-set designers and a retired cryptanalyst. We don’t do scares; we do puzzles - the kind that reward patience and a notebook.

The rooms.

Beginner rooms are gentle — no jump scares, no dark corridors. Fiendish ones are for veterans only. The duration is the timer; you can bail out at any time.

Blackout, Fitzrovia

beginner

Blackout, Fitzrovia

An air-raid warden's logbook, a missing message, sixty minutes until the all-clear.

London, 1940. You are the night shift in an air-raid warden's post in Fitzrovia. The siren has gone, the streets are dark, and a coded message dropped at the post during the last raid has gone missing - your colleague went out to deliver it and hasn't come back. A torch with a fresh battery, a stack of postcards in the wrong order, and the soft sound of bombers in the distance. Gentle, mostly logic puzzles. Good for first-timers.

Safehouse, Lyon

casual

Safehouse, Lyon

An attic above a boulangerie, a downed airman, and footsteps on the stairs.

Occupied France, spring 1944. An American airman has bailed out near Lyon and made it to your safehouse above the boulangerie. The Gestapo are working the street door downstairs - you have an hour to forge his papers, get him into the cellar passage, and convince the officer at the door that the noises he hears are the baker's wife rolling dough at three in the morning.

The Ratline

fiendish

The Ratline

Berlin, 1961. A defector, a forgery, and the Wall going up overnight.

East Berlin, the morning of 13 August 1961. A Stasi colonel has decided to come over - but he won't move without his daughter, and his daughter is on the wrong side of where the wire is going up tonight. You have your fixer's apartment, a Soviet camera, a list of border crossings being closed in real time on the radio, and a sleeve full of forged documents that aren't quite right yet. Tense, dense, several timed pieces. Veterans only.

Hut 8

tricky

Hut 8

A naval cipher to break by dawn, and the duty officer is asleep.

Bletchley Park, October 1942. Your shift in Hut 8 has just begun and a captured U-boat keyword grid has landed on the desk - but the only person who knows the day's settings has gone home with a migraine. Five tables of paper, a Type-X machine across the corridor, and a wireless dispatch the Admiralty needs by 06:00. The clock at the door is the one that counts.

How it works

Show up, get briefed, get locked in.

1. Pick a slot

Each room runs on a one-hour rotation from 16:00 to 22:30. Book online (below) or drop in if the slot is free. Saturdays book out two weeks ahead.

2. Get briefed

Five-minute briefing in the lobby. The clock starts when we leave. Hint button on the wall — use it twice and we'll just tell you.

3. Beat the room

Most teams finish with ten to fifteen minutes to spare. About one in twelve doesn't make it — honourable defeat, beer on the house.

Reserve

Tomorrow night, this weekend, or in three months.

Send us your party size, preferred room, and a date or two. We'll confirm by email within the day. No phone — we're usually inside the rooms.
