1526–27, Charles von Egmond, the last Duke of Guelders, gave permission for the building of a fortified castle in Wageningen. Some parts of the walled city were park-like, including the former Northpark (Noorderplantsoen) area. The Wageningen castle was sold in 1702 by the state of Gelderland to Anna Maria Ripperda, widow of Drost (Sheriff) Assueer Torck, and mother of the last sheriff, Lubbert Adolph Torck. The Torck family demolished part of the castle and rebuilt the other part into a small city palace with a Baroque garden. In 1722 Lubbert Torck Adolph married the wealthy widow Petronella van Hoorn, daughter of a governor-general of the Dutch East Indies. The previous year, he had inherited Castle Rosendael in Rozendaal, near Arnhem, from his uncle Johan van Arnhem. Torck was politically active as one of the mayors of Wageningen and in The Hague. He invested in the city, building mansions which he leased to pensioners of the Dutch East India Company (VOC) and other wealthy people. One such complex, the Bassecour, existing of four houses, was acquired by the city in 1876, to attract the National Agricultural College (rijkslandsbouwschool). Wageningen had several known mills. By the Middle Ages, there were two mills on the former Molenweg, now called General Foulkesweg. The last of these mills, named de Eendracht, was demolished around 1996. Once surrounded by farmlands, the 19th century flour mill, de Vlijt continues to operate on Harnjesweg. Nearby farms The various neighboring settlements were organized under the same principle structure: farms around an agricultural commons, having on the east side the arable land (at the Wageningen Eng, which was much bigger) and on the west side the meadows of the Binnenveld, evenly parcellated. The Binnenveld was farmed from the 13th century. Important farms were de Stenen Kamer in Dolder (built 1597, demolished 1954), and de Tarthorst (1731) on Tarthorsterweg, now Haverlanden (demolished in 1969). Two nearby settlements, de Peppeld (near the present restaurant 't Gesprek) and Leeuwen, remain recognizable. The characteristic livestock drinking pool (kolk) is still present on both properties. Educational institutions The Landbouwhogeschool Nederland (Wageningen Agricultural College), successor to the National Agricultural and Horticultural College, was established in 1918. This was the beginning of the special development in a small, fortified city of a specialized university that has evolved today into the present the Wageningen University and Research Centre (WUR). The Maritime Research Institute Netherlands (MARIN) was founded in
