The Sagrada Familia has a unique architectural blend of Catalan Modernism, Art Nouveau, Catalan Noucentisme, and Spanish Late Gothic designs. Although the construction of the Sagrada Familia started during the time of Art Nouveau, the architect, Antoni Gaudi was responsible for bringing the Art Nouveau style as the surface decoration much before its usual application.
As far as the existence of the Sagrada Familia is concerned, it was not meant to be constructed as a cathedral. The history of Sagrada Familia states that the construction was initiated to make it a school for the children of construction workers. Considered to have a shorter width than other cathedrals in Europe, the attraction attributes a complicated melody of parts, like three portals, several steeples, double aisles, towers, and an ambulatory with seven apsidal chapels.
The interesting things that you can observe in the Sagrada Familia are the ornament and the structure. Another thing that you should not miss catching a glimpse of in the Sagrada Familia is its interiors. The interiors of Sagrada Familia are the enclosed passages that create a rectangle around the church and move through the narthex of the three portals. You will even not find the church bragging about the exact angles inside or outside the church.
The parts of Sagrada Familia open to the public resemble a majestic castle just like in the fairytale. You will also discover the bright stained glass windows covered by excessive columns and intricately carved ceilings.
