There will be 3 main facades to the cathedral,
La Sagrada Familia. The side directly opposite the Nativity facade is the Passion facade. This side is much more dramatic and sad as compared to the Nativity facade, which is much happier and more positive.
The entrance to go inside the cathedral is on the Passion facade side.
There are cranes and scaffolding all around the cathedral as construction continues... amazing to have a community project like that, where the builders will put life work into this amazing structure and know that they might never live to see its completion.
