Stolzenfels Castle is an impressive castle perched high on a hill on the Rhine River near Koblenz, Germany. It was rebuilt in the 19th century as a romantic ruin and served as a summer residence for King Frederick William IV of Prussia.

The castle was originally built in the 13th century as a fortress to protect the Rhine and the nearby city of Koblenz. Over the centuries it was destroyed and rebuilt several times until it came into the possession of the Electors of Trier in the 17th century.

In the 19th century, King Frederick William IV bought the castle and had it rebuilt in the style of a romantic ruin. The architect of the reconstruction, Karl Friedrich Schinkel, gave the castle a unique and magnificent charm that impresses to this day.

Visitors to the castle can also enjoy the breathtaking view of the Rhine and the surrounding landscapes. The castle park and surrounding gardens offer a wonderful place to walk and relax.

Today, Stolzenfels Castle is a popular tourist destination and an important part of German cultural history. The castle is part of the UNESCO World Heritage Site Upper Middle Rhine Valley and attracts thousands of visitors from all over the world every year.
