Every year on 20 January (the feast of Saint Sebastian), the people of San Sebastián celebrate a festival known as the "Tamborrada". At midnight, in the Konstituzio plaza in the "Alde Zaharra/Parte Vieja" (Old Part), the mayor raises the flag of San Sebastián (see in the infobox). For 24 hours, the entire city is awash with the sound of drums. The adults, dressed as cooks and soldiers, march around the city. They march all night with their cook hats and white aprons with the March of San Sebastián.
