We visited last year Donaustauf, a small town in Bavaria. It is located 5 km east of Regensburg at the foothills of the Bavarian Forest. It was the first time that I stepped on this castle inspite seeing it for a couple of times when visiting Donaustauf. We can also see this castle especially when we visit the famous Walhalla Temple of King Ludwig I or Bavaria. The ruins of this medieval castle which is presumably erected between 914 and 930 is towering on this small town of Donaustauf. This is one thing I love about Germany and Europe as a whole. It is simply full of interesting and historical places and architectures!
