Most impressive part of Sagrada Familia is a Nativity Facade. It seems, that Gaudi was intending demonstrate by it the all plastic power that could be achieved in Sagrada Familia.
The work under the Nativity Facade started in February 1894 and lasted until the end of the 20th century first quarter.
Four bell towers of facade were completed in 1929, their pinnacles in 1932. The work under the sculptures of facade continued during the next few years.
The Nativity Facade has three porticos and four bells. Porticos are dedicated to the three canonical virtues. Central portico dedicated to the Charity, the portico of the right side dedicated to the Faith and the portico from the left is dedicated to the Hope.
The central portico is also called Love. The portico designed as if it is a big cave and depicts the scenes of Birth of Jesus
