Sagrada Família

The Basílica de la Sagrada Família is the reason many people come to Barcelona, and it still manages to exceed the hype. Construction began in 1882; a year later the young Antoni Gaudí took over and spent the rest of his life on it, living in his workshop on site in his final years, until he was struck by a tram in June 1926 and died days later. Gaudí knew he would never see it finished — "my client is not in a hurry," he is supposed to have said — and the building has risen ever since on donations and ticket revenue, guided by his plaster models and geometry. In 2026, the centenary of his death, the project reached its most symbolic milestone: the cross on the central Tower of Jesus Christ was completed on 20 February, bringing the basilica to 172.5 metres and making it the tallest church in the world, and Pope Leo XIV blessed the tower during a centenary Mass on 10 June. Inside, the effect is unlike any cathedral you have visited. Columns branch like trees toward a vaulted canopy, and stained glass — cool blues and greens on the east side, fiery reds and oranges on the west — turns the nave into a slow-moving wash of colour as the sun crosses the sky. Outside, the Nativity façade, the part Gaudí saw built, drips with sculpted life; the Passion façade opposite, by Josep Maria Subirachs, is angular, stark and deliberately harrowing. The Glory façade, which will be the main entrance, is still under construction. Entry is by timed ticket only, and slots — especially those that include a tower climb — routinely sell out days or weeks ahead in busy seasons, so book as soon as your dates are fixed.

Understanding the plan makes the visit richer. Gaudí designed eighteen spires: twelve for the apostles, four for the evangelists, one for the Virgin Mary and the tallest, at the centre, for Jesus Christ. The Tower of the Virgin Mary was completed in 2021 and crowned with an illuminated star; the evangelists' towers followed; and with the central tower's cross in place in 2026, the six great central towers are complete externally, though interior work on the central tower continues into 2027 and 2028 and a viewpoint inside it is not yet open to visitors. Pope Benedict XVI consecrated the church as a basilica in 2010, so this is a working place of worship as well as a monument, and Gaudí himself is buried in the crypt, where Mass is still celebrated. Below the nave, the museum explains how the building is made — the hanging chain models Gaudí used to find his arches, the plaster workshop, and the computer modelling that let later architects translate his geometry into stone.

Visiting well: the standard ticket includes an audio guide and roughly ninety minutes inside, though you may stay longer once you are in. Guided tickets add context that is genuinely useful here, and tower tickets let you choose either the Nativity or the Passion tower — you go up by lift and come down by a narrow spiral staircase, so they are unsuitable for young children (under-sixes are not allowed), anyone with mobility problems or anyone claustrophobic. The light inside is the reason to think about timing: morning sun fires the eastern glass, but late afternoon, when the low sun pours through the western windows, is the moment many visitors remember. Arrive a little before your slot for security screening, keep bags small, and dress respectfully, with shoulders covered, as it is a church. Hours shorten in winter, and the basilica can close to visitors for religious services and special events, so check the calendar before you book.

Around the basilica, walk round to see both façades from the small parks on either side — Plaça de Gaudí, with its pond, gives the classic reflected photograph of the Nativity side. The surrounding streets are heavily commercial, so do not plan to linger for lunch; instead, walk ten minutes up the diagonal Avinguda de Gaudí to the Hospital de Sant Pau, Domènech i Montaner's modernista hospital complex, or ride the metro to Passeig de Gràcia for Casa Batlló and La Pedrera. If you only have one paid sight in Barcelona, make it this one, and book it before your flights if you can — it is the single most frequently sold-out ticket in the city, and the experience of standing in that forest of light is worth arranging a trip around.
