Heldenburg Castle
Description
Heldenburg, also known as Burg Salzderhelden, was built in the 13th century to protect a nearby salt spring. It served as the residence—at times the main seat—of the Dukes of Grubenhagen (a branch of the Welf dynasty) from 1291 to 1596.
The castle’s name likely derives from “Halde” (slope). In 1361, Duke Albrecht I used a right-facing horse in his seal, which later became the Saxon Steed, the symbol of Lower Saxony.
Architecturally, the site was a four-wing complex around a square courtyard. Remnants include parts of the palas, chapel, tower, spiral staircase, and cellars. The central well is still visible.
The castle saw several sieges, notably in 1365, possibly being the first in Germany defended with a cannon. By the late 16th century, it was abandoned after the Grubenhagen line ended.
After centuries of decay, parts of the castle were restored in the 1980s. Today, it is managed by a preservation society, and open to visitors via guided tours. Ongoing excavations and conservation efforts continue to uncover its medieval history.
