Burg Entenburg, Former moated castle in Pfohren, Donaueschingen, Germany

Burg Entenburg is a former moated castle near the Danube in Pfohren, now part of Donaueschingen. It has a square main building that was once surrounded by a moat, now filled in. Depictions often show four corner towers, but whether these ever existed is disputed. The building was completely rebuilt in 1871 and restored from 1987 to 1989.

The castle was built around 1471 during a period when many fortifications were constructed across German territories. This era required defensive structures to protect settlements and maintain territorial control against external threats.

The name Entenburg is attributed to Emperor Maximilian I, who stayed three days at the castle in 1499 and is said to have given it the name Enthaburg. A local legend claims Emperor Charles the Fat died here during a duck hunt in the surrounding marsh and now haunts the site as a "Schnufer"; in fact he died at Neudingen.

Burg Entenburg is privately owned and not open to visitors, so it can only be viewed from outside; the moat that once surrounded it is gone. It stands near the Danube in Pfohren, a district of Donaueschingen, at about 686 m above sea level. The building was converted in 1871 and restored between 1987 and 1989 by Ralf and Anne Röver of Überlingen in consultation with the Freiburg heritage office.

A local legend says Emperor Charles the Fat died here during a duck hunt in the surrounding marsh and now haunts the site as a "Schnufer"; in fact he died at nearby Neudingen. The castle is privately owned and once housed an antiquarian bookshop.
