"A las Barricadas" ("To the Barricades") was one of the most popular songs of the Spanish anarchists during the Spanish Civil War. "A las Barricadas" is sung to the tune of "Whirlwinds of Danger" ("Warszawianka"), composed by Józef Pławiński. The lyrics were written by Valeriano Orobón Fernández in 1936, partly based on the original Polish lyrics by Wacław Święcicki.
