Arbesbach Castle is a top highlight that you should definitely plan a visit to. Even from a distance, you can recognize the so-called "Waldviertel's fang" (Stockzahn des Waldviertels). Once you arrive at the site, 126 steps lead up to the entrance where admission (currently €2.50) is payable in coins or by card. Then it continues inside upwards to the platform, which offers a fantastic view. There is also a circular path around the tower, which however requires some surefootedness and suitable shoes.

If you have time, you should definitely see the castle's interior. But be sure to check the opening hours. You can also stop for refreshments in the castle tavern. Good food!

The village was first mentioned in 1246 and was originally owned by the Kuenring line of Weitra-Rappottenstein. In 1282, the estate passed to the Lords of Falkenberg, and in 1291 to Ulrich von Kapelln. In the 14th century, Arbesbach is mentioned as a freehold property. From 1326 to 1348, it was owned by the Lords of Klingenberg, who in 1347 mortgaged "the castle and the house at Arbesbach" to Weikart and Katharina von Winkl. From 1348, Arbesbach was owned by the Lords of Dachsberg, and from 1423 by the Lords of Starhemberg. In 1480, the castle was destroyed by a Bohemian raiding party and was not rebuilt. In 1600, the estate passed to the Lords of Tschernembl, and in 1604 to Georg Fenzl von... Grueb and as early as 1605 to Georg Kaspar von Neuhaus. From 1614 owned by the Lords von Hackelberg, from 1675 to 1862 by the Countess Dietrichstein. Afterwards, it passed to the Herberstein, Geusau, and Baron Holtz families, and from 1877 onwards to the Altzinger family, who still own the estate today and reside in part of the castle complex.
