Secret world beneath Hungarian capital —
A maze of cavern networks lurks beneath the hills of Budapest. Many caves are open to the public for tours or guided spelunking adventures.

Mattyas Hill caves —
The longest cave system in Hungary is located under the Mattyas Hill. A small part of the complex is open to adventurous tourists and geologists training to explore more inaccessible caverns.

Gellert Hill cave —
In the 1920s, the Gellert Hill cave was used by a group of Pauline monks who built an entrance inspired by similar rock constructions in Lourdes, France. It was a chapel and a monastery between 1926 and 1951.

Danube landmark —
Opposite one of Budapest's famous spas, the Gellert Hill cave overlooks the Danube river. According to legend, the cave was occupied by a hermit centuries ago.

Castle Hill Labyrinth —
After 6 p.m. it's lights out down in the Labyrinth. Each tour team is given a gas lantern and has to navigate their way around the pitch black caves.

The Hospital in the Rock —
Located beneath Castle Hill, one local cave was used as a hospital in World War II. Conditions were cramped and the air was nearly unbearable due to the number of patients.

Uprising role —
During the wartime Soviet Siege of Budapest, doctors and nurses treated thousands of casualties here. The hospital also operated during the Hungarian Uprising in 1956.

Beneath Buda Castle Hill —
The former hospital is hidden among nearly six miles of natural caves and tunnels located directly below Buda Castle Hill.

Cold War bunker —
Under the shadow of the Cold War in 1958, the former hospital was expanded into a nuclear bunker, which could be used in a chemical or nuclear attack.
