The travel text describes the town of Freiwaldau, where there is a ruin of a Piast castle that supposedly belonged to the Bishopric of Wrocław. Mention is made of the numerous fires that consumed the castle, including when Duke Charles Ferdinand was Bishop of Wrocław. A further note mentions a Polish memorial plaque placed on the left front wing of the castle (Source: Tygodnik Illustrowany, Warsaw 1880, Series 3, T:9, p. 413, after: University of Łódź Digital Library).
