When you walk back from Potsdam you are greeted by the Schinkel designed Chateau Glienicke. We did not visit it but could gleem a lot from the outside.
From all this we were tired. Soon our bus arrived and we took it back to Wannsee station.
After a quick train trip we were home again in our Tiergarten district and our multi story apartment building was greeting us through the autumn leaves.
