The starting point for the Sagrada Familia was Gothic architecture, which Gaudí modified and improved on to offer a new architecture which, due to its originality, makes this temple unique.
The Expiatory Temple of the Sagrada Familia is a church with a central nave flanked by four aisles, and transepts with a central nave flanked by two aisles, forming a Latin cross. The top of the cross is closed by the semi-circular apse. The basilica also has three monumental facades, each one representing one of the three crucial events of Christ’s existence: his birth (C/Marina); his Passion, Death and Resurrection (C/Sardenya); and his present and future Glory (C/Mallorca).
