Abstract

This article examines the earliest construction phase of Książ Castle, which due to the ambiguity of written sources and extensive structural transformations of the building, is difficult to determine unambiguously. Based on research results conducted in 2022 and 2023, the authors attempted to reconstruct the origins of this structure.

The research involved accessing the oldest castle walls to observe the materials used, stone arrangement methods, mortar compositions, joints, and connections. These investigations were conducted in many previously inaccessible locations: inside the main tower, at the foundation level of the upper castle’s defensive walls, in cellars under the northern and southern wings, and in the gap between the upper castle and the 20th-century western wing.

The research confirmed that the main tower functioning as a bergfried with a deep dungeon could have been built at the earliest in the last two decades of the 13th century. A complete novelty was the finding that simultaneously with it, or slightly later, the perimeter wall of the upper castle and the northern wing were erected – a two-story residential building merged “back-to-back” with this wall, beneath which was a brewery cellar. The sheer scale of the structure suggests that the castle was intended to serve as a permanent ducal residence rather than a solitary fortress manned by a castellan. The construction timeline of the southern wing was also discussed in a new chronological context. Until now, it was considered the oldest after the main tower. Current architectural research indicates it was the final stage of early castle development, situated on the external side of the perimeter wall on a steep, inaccessible slope descending toward the Pełcznica River gorge due to courtyard space limitations. Its imposing form, reinforced on the slope side with three buttresses, took the form of a donjon – an extensive residential-defensive tower.

In light of the conducted research and references from 1290–1293 titling Duke Bolko I the Harsh as lord of Fürstenberg Castle, the function of Książ’s upper castle as Duke Bolko I’s residence can be confirmed. The monumental structure became a manifestation of Bolko’s power over the duchy, which from being the poorest part of Silesia, became the most important political entity in the region under his rule.
