Walkenried abbey bought more houses and land in Goslar59. The Woldenberger
urban estate (Stadthof) became the most important place of business of the
Walkenried church in Goslar. It is likely that the Cistercians concentrated most of
their business dealings at this urban estate (SCHICH 1980, 231).
In the comprehensive privilege issued by Emperor Otto IV. in 1209 a urban
estate in Würzburg is also mentioned: curiam et vineas ipsius in Herbipoli et ejus
pertinentiis sitas60. To what extent the products of the mining activities of the
Cistercians in the Harz were sold at the market in Würzburg cannot be
established from this document. The mention of vineyards owned by the
monastery seems to point to the fact that the Walkenried monastery obtained its
wine from there. In the year 1216, several nobles, with the approval of Bishop
Otto of Würzburg, sold an estate in Würzburg to the Walkenried monastery for
42 silver marks61.
In the year 1305, Albrecht II., Duke of Brunswik, left two estates in Göttingen
to the Walkenried monastery. This property was rounded off with the purchase of
two more estates in 1327. The Walkenrieder urban estates (Stadthöfe) in
Göttingen were managed in 1329 by the convert (Konverse) Helwig, whom the
monastery appointed as rector62. For a long time, the monastery in Göttingen was
obliged to pay property tax for three estates. This payment of four pfennigs
annually was waived in the year 1346, so that one may assume that the
Walkenried monks continued to use and manage these urban estates63.
In a document issued on the 25th of April 1341 by Bishop Albrecht of Hal-
berstadt permission was granted to the abbey to establish a monastic estate
(Klosterhof) in Osterwieck which was to be exempted from all levies. Shortly
after that the abbot and monastery, with the approval of the city council, bought
an estate from Konemann and Friedrich of Winnigstede inside the city walls not
far from the Nikolaus chapel for 24 silver marks64. The town on the Use lies half
way between Goslar and Halberstadt. It may be concluded that Osterwieck served
as a stopover for the transport of metal products from Walkenried to the east.
