If you had a local guide with you, he would have shown you the palace window leading into this garden, where three people were thrown out on 18 May 1618. Two royal governors and a scribe. This act began the Thirty Years' War, in which about a third of Europe died as a result of the hardships of war.
At that time, however, there was no garden, but a dump in the undergrowth. It saved the lives of three people thrown out of a window.
Like any place, there are stories attached to these gardens that the average tourist cannot discover in a visit of a few days.
Oh, that's so sad to hear!! Indeed, it's unfortunate not to find all the story behind the places you explore in the absence of a local guide. But thank you for sharing the info!
