The City of Küstrin is located next to the river Oder. This town has a long history. It is said that Fredrich II boyfriend was excecuted in the Schloss courtyard in 1730.
Today it is a part of Poland, but until 1945 it was one of the cities located along highway 1 going to Königsberg. In 1945 most of the towns in eastern germany was turned into fortresses and so was Küstrin. Since the town was heavely fortified the Russians decided to cross the river north and south of Küstrin. But it was only a matter of time before the final battle of the town could begin. Küstrin was afterall know as the key to Berlin. The fighting was very severe and left many casualties. The only that remains today is the house foundings. Below you can see some pictures from the area.
