House of Waldburg

[1] In 1258 the fief of Alttrauchburg had been given to the stewards of Waldburg, who purchased it outright in 1306 from the count, who had run into debt.

To the south, the large outer bailey was laid out together with its strong, rectangular, advanced tower.

As a result, the Waldburgs mostly lived in the castle by themselves or let had it managed by vogts (1418 Hans von Mühlegg).

As a result of suffering capture and damage in various conflicts, the castle of Alttrauchburg was expanded and strengthened in the 16th century and upgraded into a representative seat of territorial lordship and government.

In 1772 the Jacobian line of the Waldburgs died out with Count Francis Charles Eusebius.
