Nativity Façade.
The Nativity façade is the unique PART of the temple directly built by Gaudí.
When Gaudí died in 1926 only the tower of San Barnabas was totally finished and the other three very much advanced. This façade has been recently declared WORLD HERITAGE by the UNESCO.
It is formed as the other façades by four bell towers of square plant in its base, that comes to be a cylindrical structure when arrived at one fourth of their height. Further up, they come to a parabolic profile to become a pinnacle that crown each one of the towers.
The three spaces remaining among the edges, are take up by three entries forming the portico.
