Construction began in 1882 and continued after Gaudi's death in a tram accident in 1926, with the church still under construction today. The church features 18 towers representing the 12 apostles, 4 evangelists, the Virgin Mary, and Jesus Christ, as well as three grand facades representing faith, hope, and charity.
