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.

In the course of a land reform in Lower Saxony in 1972, 20 localities were added to the city through the "Wolfsburg-Act". Wolfsburg gained the status of major city with nearly 131,000 inhabitants. The city's area grew from 35 to nearly 204 square kilometers. In 1973, the city's population peaked at 131,971.
