1. La Sagrada Familia, Barcelona, Spain
La Sagrada Familia, one of Europe’s most iconic landmarks, is a prime example of overtourism. The unfinished basilica attracts millions of visitors every year, leading to overcrowded conditions, long waits, and the uncomfortable sensation of being packed in like sardines.
Despite the awe-inspiring architecture by Antoni Gaudí, tourists often struggle to fully appreciate its beauty due to the massive crowds. Arriving early or opting for a quieter season can help mitigate the chaos.
