The Lost Blueprint

✦ ✦ ✦

Barcelona, 1909. As the towers of the Sagrada Família climb above the city, a rumour spreads: Antoni Gaudí has completed one last creation. Not a church. Not a palace. A blueprint — said to reveal the hidden geometry that binds Barcelona's masterpieces into a single work of art.

Before it could be unveiled, the blueprint vanished.

To protect it, its secret was divided among five trusted guardians, each keeping one fragment. A century later the fragments have begun to resurface. Retrace their steps, reconstruct the blueprint — and uncover the identity of the shadow who has watched over it all: the Dragon.

How it works

Real streets. Real clues. One cipher.

✦ ✦ ✦
STEP 01

Read the city

At each masterpiece, a durable detail you read off Gaudí's stone and iron — a magic square, a rooftop, a wrought-iron beast — gives you a secret number.

STEP 02

Work the cipher

Set your decoder wheel to that number and decode the guardian's hidden message. Nothing is handed to you — you crack it yourself.

STEP 03

Reconstruct the blueprint

Each guardian gives up one letter. Together the five name the secret — and reveal who the Dragon truly was. Stuck? The handler gives nudges, never answers.

The sixth card

The Dragon

His emblem hides on seals, in mosaics, in ironwork and secret symbols across the game. He is always watching, yet no one ever explains who he is — a wealthy gentleman in a dragon-patterned cloak, a dragon-headed cane, his face lost in shadow. Reconstruct the blueprint, and the Dragon's true identity is finally revealed.

The trail

One walk through Gaudí's Barcelona

✦ ✦ ✦

A ~4 km route down from the Sagrada Família through the Eixample to the old city — five masterpieces, one blueprint. No spoilers: the puzzles are yours to crack.

Questions, answered

✦ ✦ ✦
Do I need an app or signal?

No app to install — the whole game runs in your phone's browser. After you pay you get a private link to your digital field kit, a decoder wheel and a handler for hints. You just need one phone per group and a little mobile data.

How hard are the puzzles?

Clever but fair. Each stop is a small 2–3 step puzzle you solve by reading Gaudí's real details, then one simple cipher you learn once and use at every masterpiece. If you're stuck, the handler gives escalating nudges — never the full answer.

Is it a guided tour or a self-guided walking tour of Barcelona?

It's a fully self-guided walking tour of Barcelona — no guide, no fixed start time. You follow the story on your phone at your own pace. It's the freedom of a walking tour with the challenge of an outdoor escape game.

How is it different from an escape room?

It's an outdoor escape game played across the real streets of Barcelona. Instead of one locked room, Gaudí's city is your board — you read clues off the Sagrada Família, La Pedrera, Casa Batlló, Plaça Catalunya and Palau Güell.

Do I have to pay to go inside the monuments?

No. Every clue is solved from what you can see from the street or square — you never need a paid ticket to any monument to play.

Is it a good activity for couples, friends or families?

Yes — it's built for 2–6 people, which makes it a great thing to do in Barcelona for couples, groups of friends or families. You solve the mystery together while walking the city's most famous Gaudí sites.

How long and how far?

About 2 to 2.5 hours over a ~4 km route, mostly flat and downhill from the Sagrada Família to the old city. Go at your own pace and stop for tapas anytime.
