Barcelona's Sagrada Familia Faces Overtourism Crisis as New Photos Reveal Secret Underground City Beneath Basilica
New leaked drone footage of the Sagrada Familia uncovers a sprawling, previously hidden subterranean complex beneath Gaudi's masterpiece, as city officials scramble to limit daily visitor caps to 5,000 amid safety concerns. Construction crews accidentally breached a sealed chamber last week, revealing ancient Roman aqueducts and a 19th-century crypt unknown to historians. The discovery has accelerated the church's controversial completion deadline to 2026, with investors now eyeing a $2 billion underground museum concept. Tourism revenue in Barcelona is projected to plunge 30% as authorities enforce the strictest access controls in the basilica's history starting next month.
