Gaudí's Sagrada Familia: a temple of satanic devotion?
On 20 February 2026, the final piece of the cross crowning the Tower of Jesus Christ was hoisted into place, bringing the Sagrada Familia to 172 metres and making it the tallest church in the world. Yet beyond the architectural milestone, a strand of symbolic analysis claims the basilica conceals a deliberately occult design. Subirachs' magic square, the "Marian" star installed in 2022 and key dates — such as the unofficial inauguration planned for 10-11 June 2026, coinciding with the centenary of Gaudí's death and 64 days before a solar eclipse — keep the suspicions alive.
The magic square of Judas and other controversial symbols
One of the most frequently cited elements is the relief by sculptor Josep Maria Subirachs on the Passion façade, which contains a 4x4 magic square whose constant sum is 33, the age of Christ. Critics, however, point out that the square repeats the numbers 1 and 14, which combined with other arrangements adds up to 66, a figure linked to the number of the beast in some interpretations. Subirachs was born on 11 March, the date of the Madrid train bombings and also associated with other tragic episodes such as the 33rd anniversary of the Alcàsser murders or the 44th of the colza oil poisoning. For believers in the satanic theory, none of this is coincidence.
The Guasonic connection and the Cerdà Plan
The most detailed analyses suggest the Sagrada Familia is part of a wider symbolic web that includes Barcelona's Cerdà Plan, designed by Ildefons Cerdà, and the city's Kabbalistic geometry. The orientation of the streets and the basilica's position would create alignments with the Montserrat sanctuary, famous for its black virgin and for housing works by Subirachs. Some studies claim Gaudí drew inspiration from the Salnitre caves of Montserrat for the towers, and that the architect worked on the sanctuary's Stations of the Cross. The open question is whether this was an innocent aesthetic influence or a deliberate chain of hidden symbols.
The official response and the papal visit
Against these theories, the Catholic Church stands firm: the Sagrada Familia was consecrated by Benedict XVI in 2010, elevated to basilica status and is a place of regular worship. Pope Leo XIV is scheduled to visit Barcelona in June 2026 to inaugurate the Tower of Jesus Christ, an event the Holy See presents as a milestone of faith. Sceptics, however, note that the chosen date — 10 June — is the same as the supposed satanic "witches' sabbath" some predict, and that the previous pope, John Paul II, also visited Barcelona on dates tied to Marian symbolism.
Mixed feelings among visitors
It is not all theories: many visitors say they feel deep unease walking through the basilica's interior, describing it as "inhuman" or "eerie". Others, by contrast, consider it a masterpiece of light and structure. Supporters of the satanic theory argue that this sense of disquiet is precisely the energy the designers were after: a space that invites not prayer but fascination with darkness. The fact is that, to this day, the Basilica of the Sagrada Familia remains both a tourist magnet and a mystery wrapped in stone.
