Hagendenkmal, Bronze monument near Rhine River in Worms, Germany

The Hagendenkmal is a galvanoplastic bronze figure designed by Johannes Hirt, set on the base of the municipal Rhine crane on the Worms riverbank. It shows Hagen von Tronje casting the Nibelung treasure into the Rhine, the moment described in the Nibelungenlied. It has stood under monument protection as Worms' main testimony to early 20th-century Nibelungen reception.

The bronze galvanoplasty was designed by Johannes Hirt and erected in 1905 in the Stadtpark, donated by Cornelius Wilhelm von Heyl zu Herrnsheim for the planned rose garden there. It stood at the northern foot of the later-raised Äschebuckel until June 1932, when it was moved to the Rhine bank onto the base of the municipal Rheinkran. It is regarded as Worms' most important testimony to the Nibelungen reception that gained strength in the early 20th century.

The monument takes its subject from the Nibelungenlied: after Siegfried's death Kriemhild gave away the Nibelung treasure to win followers, so Hagen, fearing an army, stole it during King Gunther's absence and sank it in the Rhine at Lochheim. The bronze was donated by Cornelius Wilhelm von Heyl zu Herrnsheim for the rose garden planned in the Stadtpark. Since 2021 the land-art project Kriemhilds Rosengarten by the conceptual artist Eichfelder stands next to it.

The monument stands on the municipal Rhine crane pedestal on the Worms riverbank, where it was moved in June 1932. It is a short walk north of the cathedral along the Rhine promenade. The bronze is a galvanoplastic casting, so the surface is hollow and thin-walled rather than solid cast.

The statue was originally placed in a different location within the city parks before being moved to its current spot by the river. This relocation nearly a century ago shows how the city has reorganized its monuments over time.
