In his organisation of the park, Frederick continued what he had begun in Neuruppin and Rheinsberg. During his stay as Crown Prince in Neuruppin, where he was commander of a regiment from 1732 to 1735, he ordered that a flower, fruit and vegetable garden be laid out in the grounds of his abode. He already deviated here from the classical organisation of baroque gardens, which concerned themselves purely with the model represented by Versailles, by combining the beautiful and the useful. He also followed this principle in Rheinsberg. Apart from the transformation of the palace, which Frederick received as a present from his father Frederick William I in 1734, he ordered the establishment of fruit and vegetable garden areas enclosed by hedges. In addition the central avenue and a larger intersecting avenue did not lead directly to the palace, as was usual in French parks of the era, but took off from the south wing and at a right angle to the building. Frederick invested heavily in the fountain system of Sanssouci Park, as water features were a firm component of baroque gardens. But the Neptune Grotto, finished in 1757 in the eastern part of the park, was used just as little for its intended function as the fountain facilities. Atop the Ruinenberg, roughly six hundred metres away, was a water basin from which no water could arrive into the park and because of the "fountaineers"' lack of expertise the project failed.
