Wolfer was granted lands beyond the Austrian border, most of his estates laid in the valley of stream Strém (or Strem) and centered around the hill of Küszén.

[2] In 1157, Gervasius, Bishop of Győr contributed and permitted the foundation of a Benedictine abbey at the top of the mountain of Küszén, to comes Wolfer, who donated several surrounding lands and vineyards to the monastery.

In an anachronistic way, the chronicles also suggest that Wolfer erected a "wooden fort" there, but decades later, the castle of Németújvár (Güssing) was built based on the abbey's stone walls.

[4] According to a letter of Pope Honorius III in March 1225, the Pannonhalma Archabbey was able to appoint three abbots to the monastery of Küszén in the previous decades, before "King Béla took it with the promise that, in return, he would give another place suitable for building church and estates as accessories".

[3] In that year, Béla IV and his wife, Queen Maria Laskarina donated the lordship of Vágújhely in Nyitra County (present-day Nové Mesto nad Váhom in Slovakia) and an island at Lake Balaton to the Pannonhalma Archabbey, in exchange for "the castle of Küszén, called Újvár".
