"Atlantic Ocean's Ancient Citadel Emerges After 1,000 Years"

Mont Saint-Michel, a 1,000-year-old abbey off the coast of France, celebrates its millennium since construction began. The gothic abbey, a UNESCO World Heritage site, has played crucial roles in French history and attracts 1.3 million tourists annually. However, its popularity has caused overcrowding, leading to sustainability efforts such as biofuel buses and urging visitors to explore the wider bay area. The abbey is hosting concerts, conferences, and a visual show to celebrate its birthday.
