Barcelona is a city full of secrets, and some of them hide in places you least expect.
One of the most unsettling is found on a small and seemingly quiet street: Estruc Street, right next to the bustling Plaça Catalunya.

There, at number 3, it is said that a cursed house existed, a place wrapped in superstitions, witchcraft, and strange phenomena.
Urban legend or something more?

Today we tell you all about one of the darkest mysteries of old Barcelona.

Where is Estruc Street?

The Estruc Street is a small pedestrian way that connects Plaça Catalunya with Comtal Street.
It goes so unnoticed that most tourists don’t even see it… but if you look closely, you’ll discover details that reveal its magical past.

📍 Exact location: Carrer Estruc, 08002 Barcelona

The name “Estruc” already gives clues: in old Catalan, “astruc” is associated with “warlock” or “sorcerer”. It is said that Astruc Sacanera, a wizard who used a magic stone for healing purposes, lived there.

What happened at number 3 Estruc Street?

According to popular chronicles, number 3 Estruc Street was famous in the 16th and 17th centuries for being associated with witchcraft and black magic activities.

It was said that:

Several people accused of practicing witchcraft lived in the house.
There, secret rituals, invocations, and potions were performed.
Some accounts even spoke of inexplicable phenomena: noises in the night, strange lights, mysterious disappearances.

Over time, the house gained a fearsome reputation: whoever lived there suffered misfortunes.

The Curse of Number 3

Urban legends assure that several families who tried to inhabit the house:

Faced sudden illnesses.
Lost fortunes inexplicably.
Or fell into madness or premature death.

The best-known story speaks of a young maid who, after starting work in the house, began to have visions and was found days later wandering aimlessly through the city, muttering nonsensical phrases.

Reality or Suggestion?

Historians and folklore scholars believe that the cursed fame of the house could have several explanations:

Exaggerated stories: The street’s reputation as a place of wizards could have fueled all kinds of rumors.
Unsanitary conditions: In past times, houses in poor condition were hotbeds of diseases, which were sometimes interpreted as “curses”.
Psychological effect: Living in a place marked as cursed can generate fear, anxiety… and real symptoms.

Even so, many Barcelona residents today prefer not to tempt fate by passing number 3 at night.
