Antoni Gaudí's unfinished masterpiece has been under construction since 1882 and is scheduled for completion in 2026. The nativity and passion facades, forest-like interior columns, and extraordinary stained glass represent the culmination of Catalan Modernism.
The Basilica de la Sagrada Familia on Carrer de Mallorca in the Eixample district of Barcelona is the defining work of Catalan architect Antoni Gaudi i Cornet and one of the most ambitious ongoing construction projects in history. Gaudi took over the project in 1883, a year after its foundation by bookseller Josep Maria Bocabella, and devoted the final 43 years of his life to it exclusively. At his death in 1926 — struck by a tram on Carrer de Granvia — only the crypt and part of the Nativity Facade apse were complete. The basilica is a UNESCO World Heritage Site, inscribed in 2005 as part of the Works of Antoni Gaudi. The exterior presents three monumental facades. The Nativity Facade on the northeast, the only facade largely completed under Gaudi's direct supervision, depicts the birth and childhood of Christ in dense naturalistic stone carving; its four towers are decorated with fruit, vegetation, and ceramic mosaics bearing the names of the Evangelists. The Passion Facade on the southwest, designed by Gaudi but sculpted from 1986 by Josep Maria Subirachs, takes a deliberately austere and angular character to convey the suffering of the Crucifixion. The Glory Facade on the southeast remains under construction and is planned as the principal entrance. The interior, completed in its main nave in 2010, embodies Gaudi's structural and organic vision most fully: branching stone columns inspired by a forest canopy transmit loads through hyperboloid and paraboloid surfaces without conventional flying buttresses. The central nave rises to 45 metres. Stained glass designed under Gaudi's principles bathes the interior in amber and golden tones from the east and blue and green light from the west, shifting dramatically through the day. The central tower dedicated to Jesus Christ, at 172.5 metres on completion, will be the tallest religious building in Europe. Construction funding comes entirely from entrance fees and private donations. Eight of the planned 18 towers are complete as of the mid-2020s. After Gaudi's death, work continued from his plaster models and drawings, many of which were destroyed in 1936 and have been reconstructed using computer modelling.
Why it matters
The Sagrada Familia is the most ambitious example of Catalan Modernisme and the life work of Antoni Gaudi, representing a unique and still-incomplete synthesis of Gothic structural tradition and naturalistic organic form that has influenced architectural education globally since the 20th century.

Tips for visiting
- Book timed-entry tickets on the official Sagrada Familia website at least several weeks ahead; same-day availability is extremely rare.
- Morning visits from opening time capture the best light — eastern stained glass floods the nave in warm amber tones until approximately 11 AM.
- Tower elevator access to the Nativity or Passion tower costs a supplement of approximately 9 euros and must be booked in advance online.
- Audio guides in English are included with most ticket types and explain Gaudi's full symbolic programme in detail.
- Visiting on a weekday rather than a weekend significantly reduces queuing time at the entrance gates.
- The basement museum is included in the general ticket and contains compelling original plaster models alongside photographs of construction stages.
Frequently asked questions
How long does a visit to the Sagrada Familia take?
The interior and one tower elevator typically take 1.5-2 hours. Visitors who add both tower options and the basement museum should allow 2.5-3 hours in total.
Is the Sagrada Familia suitable for young children?
The interior is visually spectacular and tends to engage children strongly. Tower elevators are subject to a minimum height restriction. Pushchairs can be used on the ground floor but may need to be folded in the tower lifts.
Is the Sagrada Familia wheelchair accessible?
The ground-floor interior is fully accessible to wheelchair users via a dedicated entrance. Tower elevators are not accessible for wheelchair users. Adapted toilets are available and hearing induction loops are installed in some areas.
When will the Sagrada Familia be finished?
The central tower of Jesus Christ at 172.5 metres is projected for completion in the late 2020s. The full complex with all 18 towers and the completed Glory Facade is expected to take longer and does not have a confirmed final completion date.
