Alt-Ramschwag Castle (Ruin) (Häggenschwil)

Of the ancestral castle of the Lords of Ramschwag, built shortly after 1200, only the ruins with tower remnants, residential and economic buildings, and a ring wall with a gate system remain today. The location of the castle ruins was carefully chosen: In the north and west, it is protected by the stream gorge and the Sitter river, and in the east by three moats.

Later, Alt-Ramschwag came into the possession of Rudolf von Rosenberg through marriage, who finally sold the castle in 1427 to Ulrich and Burkard von Helmsdorf (South German nobles).
