The labyrinth of Buda Castle
The Buda Castle Labyrinth is the largest system of caves, cellars and cells carved into the hills of Hungary's capital by infiltrating thermal waters.
In 2000 it was ranked among the 50 most interesting places of the world, thanks to the program “Labyrinth of Lanterns”: from 6 p.m., all lights are off and the visit is done using an oil lamp.
It is one of Budapest’s Top 10 most famous and visited attractions. Labyrinth of Buda Castle is regarded as one of the 7 underground Wonders of the World.
During World War II, the labyrinth served as a bunker, housed the military hospital and the Holy Crown and some of Hungary's gold stock kept here for a while. The Turks also used it mainly for military purposes in the 16th century.
