The spatial narrowness and antiquated design of the little-appreciated park at the castle in the city center gave rise to the purchase of the strongholds Anton and Ulrich in 1802 for the then Duchess Augusta. As an English princess, she had already had a landscaped park built on the model of her home at Richmond Castle, and here too at her own expense she had the ramparts converted into such a landscaped park for herself and "the pleasure of the city". The planning was entrusted to the ducal-dessauian garden inspector Johann Georg Gottlieb Schoch the Younger (1758-1826), who was then known by the important Wörlitz parks.
