The caves were fortified in the
High Middle Ages and first enter the historical record in 1181 as
Schalun (Schallaun) Castle, named for
Machward of Schalun. Burg Luegg was likely built at the same time by the local
Lueger family. Throughout the late
medieval period both castles changed hands among Styrian nobility. Schallaun was owned by a family related to the
Lords of Saurau and was sold to the
Liechtenstein family in 1472. After the extinction of the Cilli line in 1456 the Teufenbacher lords continued as
feudatories into the 17th century. Both
castles passed by
inheritance or
sale into the
Pranckh (Pux) family, who retained them as part of their estates. From the 16th century onward the
cave castles fell into decline. Luegg was probably abandoned by the 1600s as the difficult access and cramped conditions made permanent residence impractical.
Legend suggest that in the early 19th century a gang of robbers took refuge in the Puxerloch caves, the authorities reportedly destroyed much of the remaining
masonry by
explosion to
evict them. Nevertheless, the larger Luegg cave was still described as partially habitable into the 19th century. Today both ruins (and nearby
Schloss Pux) remain private property of the
Pranckh family. == Site and architecture ==
