The castle was built probably during 13th century. First written mention from 1395 appears in the chronicle of nearby town Česká Kamenice. The castle had changed hands several times. No mention exists that it was ever conquered. Falkenštejn was abandoned during 15th century.
The small castle was situated on the top of very hard to access sandstone rock - a ladder was needed to climb into it. The buildings were made of wood. Well was not available, instead deep water tank was used.
In 1825 the place was cleared to make it accessible for the tourists. It is freely opened but it takes effort to get into the castle itself.
