The ancient caves beneath Buda Castle have a colorful and sometimes disturbing history.
At the top of a hill in Budapest, overlooking the Danube River, sits Buda Castle, a gorgeous UNESCO World Heritage site visited by thousands of tourists every year. Directly underneath the castle, however, lies a less-frequented tourist attraction: a series of ancient, naturally formed caves with a colorful and sometimes disturbing history.
The entire cave system is over six miles long, and most of that has been left unchanged since it was used as cold storage (and a rumored dungeon) in the Middle Ages. Between 1939 and 2008, however, a half-mile stretch of those caves was built up and repurposed many times over.
