On one of my travels to Salzburg, Austria (We went because I was asked where I wanted to go, and I said to the Sound of Music place), and I was fortunate to visit Hellbrunn Palace.

This is where the Arch Bishop had a marble outside table with seats that had water fountains in them. No one was allowed to stand above the Arch Bishop. So if he didn't like you and you were called to dinner, he would turn on the fountain and then he could put you in prison.

I will always remember this place. As there were tiny little fountains built in everywhere, with little town scenes and they operated via the water. Absolutely Fascinating!!!
