On June 17, 2025, around 1,000 people walked through busy tourist areas in Barcelona, Spain. They were unhappy about too many tourists in the city. Some people used small plastic water guns to spray tourists. They also shouted, “One more tourist, one less resident.” This protest happened near La Sagrada Familia and other popular places. The water guns were first used in a protest last July. At first, they were used to cool down in the summer. Later, they became a sign of protest. The people said tourists make it hard to live in the city. They said prices for houses are going up, and the city feels like a theme park.

Protesters said the water guns are not to hurt anyone. A woman named Lourdes Sánchez said it is a calm way to show their feelings. An architect named Laurens Schocher said they want to speak to city leaders, not fight with tourists. Some tourists thought the water was funny, but others felt scared. Experts say tourism is very important for jobs and money in Barcelona. They believe better plans are needed to help both locals and visitors.
