History
Kasteel Hulkestein was a medieval castle and fortified observation post in the Netherlands, northwest of Nijkerk, built as the Hulckenstein blockhouse on the border of the Sticht in either 1427 or 1458 on the orders of Arnoud van Gelre, Duke of Guelders. The Sticht was the ecclesiastical territory ruled by the prince-bishop of Utrecht, making this frontier politically sensitive. From its position near Spakenburg, Hulkestein gave the duke military control over shipping on the Zuiderzee, the former inland sea later partly enclosed and transformed into the IJsselmeer.
Guelders and Burgundian control
The castle formed part of the military landscape of Guelders during its conflicts with neighboring territories. In 1473, Guelders was occupied by the Burgundian forces of Charles the Bold, Duke of Burgundy. After those troops withdrew, Charles of Egmond recovered his family’s possession of Guelders in 1492.
Hulkestein was destroyed during renewed conflict around 1516, although the precise year is uncertain. Busken Huet described its capture by forces from Holland, followed by the imprisonment of the commander and garrison, the blowing up of the castle, and the burning of nearby ships. The castle was rebuilt in 1524, restoring its military presence on the frontier.
Decline and later memory
The Treaty of Venlo in 1543 brought Guelders into the dominions of Emperor Charles V and the Habsburg Netherlands. With this political change, Hulkestein lost its military importance and gradually deteriorated into a ruin.
Members of the Pannekoeck family, who had commanded the blockhouse, reused stone from the ruin to build the Pannekoekenhuis in Nijkerk. The house was also called New Hulckenstein or the Torenhuis, a name associated with its hexagonal dovecote. A fire led to its demolition in 1851.
Hulkestein also figured in an economic project under Charles of Guelders. In the late fifteenth century, he ordered a canal to be dug from the Zuiderzee toward the Rhine near Wageningen, with the work advancing from Hulckestein toward Wageningen. Difficulties, high expense, and continuing wars brought the project to a final end in 1545. The unfinished section was later filled in or destroyed by flooding. The castle’s names survive in the Hulckesteinse Bos near Zeewolde and the Nieuw Hulckesteijn recreation area on the Veluwemeer.
Remains
Only a drawing from 1854 is known to show Hulkestein, so its appearance is only partly understood. The castle had a tower, and Bentheim sandstone was used in its construction. Bentheim sandstone is a building stone quarried in the Bentheim region of present-day northwestern Germany and historically used in parts of the Netherlands.
Submerged masonry
The former castle may have disappeared into the Zuiderzee on the Nijkerk side of the later Nijkerkernauw. Submerged walls found there in 1989 were about 70 centimetres thick and were considered possible remains of Hulckenstein. In 2024, a team of divers found a wall built from large bricks known as monastery bricks, providing further physical evidence associated with the vanished site.
Possible moat outlines
In 2007, apparent outlines of the castle moat were identified through imagery on Google Earth. These contours offer a possible indication of the former defensive enclosure, but their interpretation remains based on visual observation rather than confirmed archaeological identification.
