Following Count Louis' succession in 1780, the park saw the addition of various buildings and structures, including the so-called Greece and Egypt, as well as imitations of Oriental and Far-Eastern styles.
The oldest surviving layout dates from 1787 and includes 105 buildings, fountains, bridges, statues, islands, gardens, and paths crammed onto a 125-hectare plot.
In later years, criticism on the excessive density of objects and architectural styles and the rise of the English garden brought about substantial change to the Bagno.
Buildings and other objects were removed, new ones constructed; straight ways were replaced by meandering paths, natural looking yet artificial cascades were built, large lawns created and exotic trees planted.
The Bagno developed into the most prominent park of Westphalia boasting extraordinary fountains, a widely known chapel, and a lake navigated by a fleet of small yet pompous ships.
