Peter Joseph Lenné founded the first training center for garden culture in Europe in 1823 in Potsdam. It was his goal to promote the art of gardening in the "Royal Garden School", which he had come to know and appreciate on his extensive travels, which had also repeatedly taken him to England. In 1903, the gardening school moved to Berlin-Dahlem to the greenhouse complex, which was modern at the time and is now historic. I was responsible for the development of their new website.
