Burg Schweinberg

Burg Schweinberg is a medieval spur castle situated in the municipality of Hardheim in Germany. It was constructed by a noble family during the Middle Ages, likely in the late 11th or early 12th century. The earliest reference to the castle dates back to 1098, when it was associated with the noble family known as de Swenenburg.

During the 12th century, the castle held strategic importance due to its position overlooking a key medieval route connecting Würzburg through Tauberbischofsheim to the Lower Main region. Documentation from this period includes mentions of individuals linked to the site, such as Wolfram de Sueneburc, who appeared as a witness in a deed from Mainz in 1127. By 1157, the castle was noted under the name Suinenburch, confirming its early presence and importance.

The last known lord from the Schweinberg family, Kraft II., joined Emperor Frederick Barbarossa’s campaign in Italy in 1167 and died shortly thereafter, probably from malaria. The castle then came into the possession of Konrad von Boxberg, Kraft’s brother-in-law, who transferred it to the Johanniter, commonly known as the Knights Hospitaller, at Wölchingen. Over time, parts of the Schweinberg lordship were divided among the Edelfreien von Dürn and the Counts of Wertheim, reflecting shifts in regional power.

In 1287, an exchange arranged by Bishop Berthold II of Würzburg saw Burg Schweinberg traded with the Johanniters for Burg Boxberg. The castle was then granted to Konrad Rupert von Boxberg, who held the hereditary office of ducal chamberlain, an important administrative role. By 1299, control shifted to the Counts of Wertheim, related to the Boxberg family, who also secured the chamberlainate by 1313. They established the Amt Schweinberg, an administrative district encompassing the castle, its village, and adjacent settlements, consolidating their regional authority.

The Prince-Bishops of Würzburg continued to view Schweinberg as a fief belonging to their bishopric, leading to disputes with the Counts of Wertheim. These tensions culminated in 1437 when forces loyal to Würzburg captured and burned the castle during a feud over inheritance rights involving Michael I of Wertheim. The stronghold was rebuilt in 1473 and thereafter served as the seat of a Wertheim ministerial, a noble official managing local affairs.

Following the extinction of the Counts of Wertheim, ownership of the castle and its associated chamberlain office passed through several hands, including the Freiherr von Crichingen by the year 1574. In 1612, Prince-Bishop Julius Echter succeeded in reclaiming Schweinberg as a Würzburg fief after extended legal and military efforts, although formal conflicts over jurisdiction continued until the Holy Roman Empire dissolved in 1803. The castle endured damage during the Thirty Years’ War and gradually fell into neglect. Over subsequent centuries it was quarried for building materials before preservation efforts began, notably with the restoration of its bergfried tower in 1974.
