The Kristýnasand Quarry, Hrádek nad Nisou

This very popular outdoor swimming pool dates back to 1786, when coal began to be sought. The instigator was Count Kristián Clamm – Gallas and his estate manager Paul. They took their inspiration from the Zittau brown coal basin, where quarrying had already been under way for some time. Surveys showed deposits of lignite and several shafts were opened around the ...

The Kyselka – Mineral Spring, Nové Město pod Smrkem

A mineral spring that was discovered in 1780 is to be found in the valley of the stream known as Ztracený potok near Nové Město pod Smrkem. Emissions of carbon dioxide make their way into underground waters in the place of geological faults amidst crystalline rock and come to the surface as acidulous waters. The Nové Město acidulous spring is located on the same geological fault on which far better known curative waters are found in the nearby spas of Libverda, Czerniwa Zdroj and Swieradow Zdroj. The discovery of the acidulous spring is ascribed to mining smith Johan Nepomuk Legler, whose idea it was to tidy the access path to the spring...

The first sewers were built from the hospital to the back of the theatre in Sokolská street and were up to 2km in length...
