In San Sebastian, the greatest incidents occurred in recent decades as a result of an act of Phalanx. The fascist institutions wanted to celebrate Hispanidad on the Boulevard of the city and in response to the call thousands of anti-fascists met to fight him.

With the aim of emptying the area, the Ertzaintza loaded it against the citizens and generated and spread conflicts throughout the city center, burning dozens of containers and blocking the city.

The Falange could not enter the city and the bus from Spain had to stay in an external shopping center.
