Place des Célestins makes way for an interactive display this year, Heartbeats (Coups de Coeur) by Franck Pelletier and his collective les Allumeurs.
A huge illuminated heart will give the beat to the city and its lovers. Couples are invited to place their hands on the console to monitor their heartbeat and see if both hearts beat in unison.
On the red-lit façade of the theatre, a counter will show musical beats, with 120 songs playing over and over. Love songs, of course.
