La Sagrada Família
Construction began on La Sagrada Família in 1882, with Antoni Gaudí taking over as lead architect a year later. When he died in 1926 it was only 25% complete. Work is still ongoing, with the church finally set to be finished by 2026.
Where I found most of Gaudí’s other works rather gaudy, la Sagrada Família was excellent. The interior architecture is especially stunning. They’ve done a great job of lighting the atriums and columns, making the space far less gloomy than other churches.
The interior is rather reserved in colour pallete (unlike other Gaudí buildings), but the exterior has brief flashes of strange / bizarre / interesting mosaic.
You can pay extra to ascend one of the towers. You get an ok view of the nearby neighbourhood, as well as a closer look at the towers and some of the higher bits of the exterior.
Most of the plans and models for la Sagrada Família were destroyed during the Spanish civil war of 1936. Some have been reconstructed but much has had to be recreated or worked out from scratch. Beneath the main church a team of model makers and architects plan and make models for the parts of the building still to be finished.
