Antonio Gaudi designed this cathedral and many other buildings in Bacelona, Spain. Gaudi started work on Sagrada Familia in 1882. He died in 1926 with 15-25% of the construction complete. The cathedral is still under construction and completion is expected in 2026 on the centennial of Gaudi’s death. Gaudi’s work defied the conventions of the day and is still considered unconventional.
