Officially named Basilica I Temple Expiatori de la Sagrada Familia is the finest creation of the renowned Catalan architect Antoni Gaudi. The architect devoted over four decades to the church but at the time of his death in 1926, the spectacular building remained uncompleted. In fact, it is scheduled to be completed only in 2026, on the 100th anniversary of Gaudi’s death. But despite the fact that it is not finished, the Sagrada Familia is an UNESCO World Heritage Site since 1984 and Barcelona’s prime tourist attraction for decades.
