There is a plan to convert an unused limestone mine into a thermal spa in Diósd.
The facility will cover a 26 thousand square meters land; part of it - about 11 thousand square meters - will be built underground.
Currently the quarries are surrounded by forest, and are part of a geological park.
Mining began in this area in the eighteenth century. The stones used to build the parliament and Buda Castle were quarried from this site.
