Burg Seldeneck, Medieval castle ruins in Creglingen, Germany.

Burg Seldeneck is a castle ruin located on a hilltop near Creglingen, preserving sections of walls and arched windows from its medieval past. The site offers views across the surrounding valley landscape.

Seldeneck Castle was first named in 1265 and again in 1300; the name of Heinrich I von Rothenburg is only linked to Seldeneck from the mid-13th century, so the castle cannot be much older. It was probably founded by the father of Götz von Hohenlohe as a fief of the Bohemian King John. Gottfried installed the later Seldenecks as Burgmannen and sold shares to Conrad and Arnold von Savensheim and to his brother Kraft II, making it a Ganerbenburg. On 29 July 1404 it passed from Burgrave Frederick I of Nuremberg to Rothenburg ob der Tauber, and it was likely destroyed in 1407 during King Rupert's campaign against that city.

The castle reflects how medieval noble families shared control of their properties and lived alongside one another. This arrangement shaped local relationships and was a common practice in the region.

The ruins sit on a hilltop and require sturdy footwear for a comfortable visit due to the terrain. The location near the border between two regions is easily accessible by car from surrounding villages.

The castle hill is wooded again, so the view of the Tauber valley is limited today; in the Middle Ages Rothenburg ob der Tauber could be seen from the site. The E8 European long-distance trail from Rothenburg passes close by on its way to Creglingen.
