I was traveling the last four days. There is a lot to tell but time is the enemy. So let pictures speak:
Sparrenburg Castle, Bielefeld
Hermannsdenkmal in the Teutoburg Forest near Detmold
The Externsteine in the Teutoburg Forest near Detmold
View of a castle during a boat ride on the Rhine river.The famous Federal Guest House on Petersberg mountain (One of the seven mountains in Bonn).
