Wolfstein, Rhineland-Palatinate
Wolfstein was founded in 1275 on Habsburg King Rudolph I's orders, which called for a “fortified and free” town near his castle, “Woluisstein”, now known as the "Alt-Wolfstein" (“Old Wolfstein”) ruin. Rudolph forthwith granted the new town the same town rights and freedoms as the town of Speyer. As an “everlasting marketplace”, it was to be a sanctuary for commerce, trade and dealing. The first townsmen and -women came from the surrounding, much older villages.
Blaustein

It belonged to the families of Stain / Klingenstein. Palace and ruins went in 1860 to the property of the Ulm pharmacist and inventor family Leube. It is now owned by the Leube Foundation. The 1931 Protestant Kreuzkirche is next to the nearby Church of St. Joseph one of the few expressionist church buildings in Baden-Württemberg.
