Grotte La Merveilleuse, Underground limestone cave in Dinant, Belgium.
The cave system extends 850 meters beneath the surface, featuring numerous white calcite formations, natural stone cascades, and mineral deposits throughout its chambers.
Workers discovered the cave network during railroad construction in 1904, and it served as a shelter for local residents during World War II combat operations.
The cave hosts regular concerts and performances, connecting with Dinant's musical heritage as the birthplace of saxophone inventor Adolphe Sax.
Guided tours depart every hour between 10 AM and 5 PM from April through October, with reduced winter hours on weekends and holidays.
The cave maintains a constant temperature between 8 and 12 degrees Celsius, creating specific conditions for mineral formation processes throughout the year.
