It's been under construction for over a century. Work began in 1882 and if all goes to plan it'll be completed in 2026.
It's the most visited attraction in Spain, so book your tickets well in advance. Otherwise arrive before it opens (9am) to avoid the crowds.
Gaudí was inspired by nature and signs of this are everywhere, check out the interior supporting columns that resemble a network of trees.
Most nearby restaurants will be overpriced so try and contain your hunger until you've left the area.
Parts of the basilica were meant to be built separately so that each generation of architects could bring their own style to the work. You can see this in the three facades: the Nativity (influenced by the style of Gaudí), Passion (simpler, created by several architects) and Glory (currently in progress).
Gaudí believed no man-made work should surpass that of God. For this reason the Sagrada Família was always intended to be 1m lower than Montjuïc, the city's highest ‘natural' point.
There's a magic square on the Passion facade. It's a 4×4 square of 15 different numbers that when added horizontally and vertically always equal 33. Some say it's a reference to Christ's age when he died.
Anarchists set fire to the crypt in 1936 during the Spanish Civil War. Some of Gaudí's original plans for the Sagrada Família were lost and since then its construction has required a bit of guesswork.
Gaudí died at 73 after being hit by a tram. It's said he was mistaken for a beggar and failed to receive immediate medical attention. He's buried in the crypt.
Originally sponsored by private patrons, its construction is now funded solely by donations and ticket sales. In this way you can be a part of this immense project.
