Voitsberg is a county town (Bezirkshauptstadt), which makes it an important administrative, educational and economic centre for the area.In terms of sightseeing, Voitsberg is nice and offers the usual sights of a historic market town - yet the place is not a very touristy one.
It served military purposes, was later transformed into a more representative place and saw its end in 1877: The entrepreneur August Zang re-modelled it into a rather unappealing historicist chateaux.
Another important attraction is the Burgruine Krems; its origins can be tracked back to the 12th century.
The church of St.-Josefs-Kirche was built as a monastic church between 16 in Baroque style.
Note the former Carmelite monastery, founded in 1395 and dissolved in 1812.
Since then, the ruins serve as a venue for cultural events like the annual "Burghofspiele", a theatre festival of local interest.
