Under Elector Friedrich V the "Stückgarten", in which the cannons (also called "Stücke" in German) stood, was turned into a magnificent, world-famous pleasure garden and contributed to the fame of the ruler. The "Hortus Palatinus" was created in 1614-1619 by Salomon de Caus, who was called from London for the task.
Here herbs, box trees and bitter oranges were planted, and colorful patterns of gravel and pottery fragments laid.
This also provides more emphasis for the waterworks (fountains etc.), which play a very central role.
The high points of the garden also included artificial grottos carved into the mountain.
The Renaissance concept of an earthly paradise created by human hands became reality in the Hortus Palatinus. It unites technical, aesthetic and ideological principles to form an artistic synthesis. The Hortus Palatinus was long considered the eighth wonder of the world.
