LA MERCE fiesta is held on the September equinox, and is a 4 day mix of pagan festivals, catholic ceremony, traditions, music and parades. One of the highlights is ‘la projection’, this year the “Moment Factory” from Montreal offered a multimedia show on the Nativity facade of the Sagrada Familia, an ode to the creation of the world and man and to life itself. (Apologies for the editing).
This is the illuminated Nativity facade;
…. and this is the same facade, as you’ve never seen before.
No place like home. 
Awesome, Richard, must have been extraordinary to be there!! Also loved hearing the voices of the crowd, especially the child. Did u film this, is that your voice I can hear?
