Gutenburg Castle is the ruin of a hill castle above the village of Gutenberg in the county of Bad Kreuznach. The castle is first recorded in 1213 as castro Weitersheim. In 1334 the counts of Sponheim (Lower County of Sponheim) sold the castle, which had meanwhile been renamed the Gutenburg. After the sale it underwent a major conversion. Following the extinction of the House of Sponheim (the Kreuzenach line died out in 1414 and the Starkenburg line in 1437) the castle went to the Lower Sponheim lords (mainly the Margraviate of Baden and Electoral Palatinate). The castle lost its importance over time, was destroyed during the Thirty Years' War and fell into ruins. Today the castle ruins are in private ownership.
The castle consisted of an inner ward completely surrounded by a ring-shaped outer ward, protected by curtain walls with mural towers as well as a neck ditch. Considerable sections of the wall remain visible today.
References:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
