A large crowd of people marches down an urban street, seen mostly from behind. Many participants carry red flags; one prominent flag in the foreground features a white symbol resembling a stylized '2' or 'S', while another flag in the distance clearly displays "CGT" in white letters on a red background. A few purple and white flags are also visible further back in the crowd. The background is dominated by a very tall, cylindrical building with a distinctive glass and metal facade, reflecting a reddish hue in some sections. This building is a prominent landmark, suggesting the location is Barcelona, Spain, and the building is the Torre Glòries (formerly Agbar Tower). Green trees are visible to the left of the marchers, between them and the building. Overhead wires, possibly for a tram, stretch across the sky. The sky is overcast. The crowd is engaged in a chant or shouting, indicative of a protest or demonstration.
