N. Kósa Judit - Szablyár Péter: Underground Buda - Our Budapest (Budapest, 2002)

Bibliography

The underground miracles of Budapest are as little known to the inhabitants of the city as they are to the millions of tourists visiting here every year. These curious locations are introduced to the reader by the twin- volumes Underground Buda, Underground Pe&t.

The belt of hills on the left-hand-side of the Danube suggests, with its steep rock formations and ravines, a varied underground world. The natural cavities formed in the rock by millions of years have been extended and adapted to human needs by the inhabitants of the city. The network of natural and artificial cavities, the beds of dried-up streams locked in the embrace of stone vaults, the ducts and the ''balloons" of giant subsurface reservoirs all make a lasting impression.
