History
Löwenburg is a medieval hilltop castle ruin in Germany, located in Bad Honnef on the 455-metre-high Löwenburg mountain in the Siebengebirge. Built during the second half of the twelfth century, probably under Heinrich II, Count of Sayn, it served as a frontier fortress facing the Electoral Cologne castles at Drachenfels and Wolkenburg.
Foundation and the Lords of Löwenburg
Heinrich II was a nobleman of the Sayn comital house whose territorial interests extended from the Westerwald toward the Rhine. The castle’s former name, castrum Lewinberg, first appears in a document dated 29 August 1247. The record concerns the division of the Sayn inheritance by Countess Mechthild of Sayn, who retained the right to live at Löwenburg.
During the thirteenth century, the main castle, outer bailey, and northern outer ring wall were established. In 1269, inheritance transferred the castle to Mechthild’s nephews, members of the Counts of Sponheim-Heinsberg. The family thereafter adopted the title Lords of Löwenburg. Honnef became the principal settlement of their lordship, while one branch established itself at Merheim.
Administrative change and decline
After passing through several changes of ownership, Löwenburg came under the Duchy of Jülich-Berg in 1484. This major Rhineland principality incorporated the castle into its administrative system. The Amt of Löwenburg, an administrative district, was governed from the castle until the middle of the sixteenth century.
The Amt suffered particularly during the military campaigns at the end of the sixteenth century, and Löwenburg became a ruin. The thirteenth-century complex then continued to deteriorate. Its principal defensive tower, known as a bergfried, was partly dismantled in 1832. Structural instability led to further reduction in 1881, leaving the tower almost at the level of its surviving masonry stump. Stabilization and repair work had already been carried out in 1834, after an earlier attempt to preserve and restore the ruin had failed.
Conservation and archaeological investigation
Administration of the grounds passed in 1861 to the Royal Prussian Siebengebirge Forestry Office, predecessor of the present Siegburg State Forestry Office. Restoration followed in 1862, and most of the surviving fabric was secured between 1897 and 1901. An observation tower was erected at the castle’s highest point in July 1906, and the first excavations intended to expose parts of Löwenburg began in 1908.
At the beginning of the Second World War, an anti-aircraft observation post was installed in the upper castle in 1939. During the fighting connected with the American crossing of the Rhine, Löwenburg came under heavy shelling. The 1906 observation tower probably did not survive the bombardment. After Prussia was dissolved, the ruin became property administered by the state of North Rhine-Westphalia in 1947.
Between 1979 and 1985, the state forestry administration and the Bonn State Building Office undertook extensive stabilization and restoration. Surviving foundation walls were exposed and secured, with archaeological work carried out in cooperation with the Rheinisches Landesmuseum. The restored complex was formally inaugurated on 2 October 1985. Bronze panels made by the Königswinter sculptor Sigrid Wenzel in 1988 and 1989 portray the castle’s original appearance.
Further damage appeared in the bergfried stump during the winter of 2012–2013, prompting masonry repairs from 2013 to 2017. Archaeological excavations inside the tower stump and immediately south of it in the fortified space known as the zwinger were ordered in spring 2013. The same investigation produced the first precise overall survey of the ruin, using detailed surveying instruments and measurements derived from photographs. Löwenburg is protected as an archaeological monument, and its exposed position provides views over the Rhine valley near Bonn and toward the Westerwald.
Remains
Löwenburg occupies the summit of a weathered volcanic plug composed of nepheline latite, a volcanic rock. The summit forms an approximately east-west plateau that was at least partly created artificially during the Middle Ages. The main castle occupies the highest ground at the western end, while the outer bailey extends across the lower plateau to the west. Most walls use rough rubble stone made from local latite, with non-local trachyte and tuffs used for selected architectural elements, including the surrounds of the great hall.
Approaches and defensive works
Ring path and sunken road
A steep path arranged in a ring around the mountain leads toward the castle. In several places, the terrain preserves an overgrown older sunken road, marking the original route to the summit.
Neck ditch and outer ring wall
On the less steep southwestern side, below the outer ring wall, a neck ditch formed an early defensive obstacle. The ditch was excavated while material was being obtained for construction, and the resulting scar from extracting latite remains visible. The long thirteenth-century complex included the main castle, the zwinger, the outer bailey, and the northern outer ring wall.
Main castle structures
Castle courtyard and cistern
The castle courtyard retains a cistern, while the restored archaeological work has exposed and secured the surviving foundation walls of the wider complex.
Bergfried stump
The former bergfried, the principal defensive tower of a medieval German castle, survives as an irregularly high masonry stump. Its base measured 10 by 10 metres. Most of the tower was removed in 1832 and 1881, and the remaining masonry underwent further repair after damage discovered in 2012–2013.
Observation tower and reconstruction panels
The observation tower erected in 1906 stood at the highest point of the castle and probably failed to survive the heavy shelling of the Second World War. Bronze panels placed on the summit in 1988 and 1989 show a reconstruction of the castle’s original appearance.
Archaeological finds and visual evidence
Excavations in 2013 inside the bergfried stump and in the zwinger area recovered approximately twelve vessels made of Siegburg stoneware. These vessels are displayed at the Siebengebirge Nature Park House operated by the Siebengebirge Beautification Association. The oldest known pictorial representation of the ruin is an etching by Wenzel Hollar, based on a pen-and-watercolour drawing from 1629.
