The sobriety of Gaudí.
This work was not begun by Gaudí, he just finished it. Owing to the fact the nuns had very little money, it was built in brick but with the stamp of the great master.
The materials and shapes used in this construction are very simple, used in the exterior facade and in the corridor-cloister of the parabolic arch. The iron work of the door is marvellous as well as the religious symbols, however, what is really curious is that it does not have a lock and cannot be opened from the outside.
