September 20, 2017. The Spanish police stormed Catalan government buildings in an attempt to stop the independence referendum.

At 10:00 pm, a cacerolada began in multiple municipalities across Catalonia. The protest repeated every day at the same exact hour, until October 1, the day the referendum took place.

Due to the brutal police force deployed by the Spanish government during the referendum, the cacerolada continued for a few more days.
