A large group of people, predominantly young adults, are marching down a sunny city street. Many participants are holding and waving red flags. In the background on the left, a white banner with black text is visible, which reads "1M CONSTRUIR L'ALTERNATIVA REVOLUCIONÀRIA," indicating a May Day (International Workers' Day) protest or demonstration in Catalan, advocating for building a revolutionary alternative. The street is lined with multi-story apartment buildings, some with balconies, and mature trees with green foliage provide shade. Blue parking signs are also visible on the right side of the street. The weather appears bright and clear, suggesting daytime.
