These were the first doors that were placed in la Sagrada Famila in 2015! (before that, there were no doors in the temple). They are part of the Nativity façade, the one that was done when Gaudí was alive.
The doors are the ones in the centre of the façade, in the Charity portal. The doors are represented full of green ivy leafs. Etsuro Sotoo, the Japanese sculptor who built them, stated that the Ivy is the element in the nature that represents better the love. Indeed the doors are dedicated to Mary and Joseph. The doors are made of Bronze. It was on purpose, since bronze is a metal that, the more it gets touch, the more brilliant and beautiful it becomes like the love between two people.
