Introduction to the Old Bridge: The Old Bridge on the Main River is the most beautiful bridge in Würzburg and on the Main River. It is the only way from the castle to the old city. The Old Bridge was built in the 15th century. The statues on the bridge are religious saints or local historical celebrities. From the bridge, you can not only see the castle, the grape fields on the mountains, the clear water of the Main River, but also the scattered church spiers in the old town of Würzburg, which is the most beautiful scenery in Würzburg.
