Renchen was first in official documents in 1115. In 1326 it received a city charter but the city lost it again as well as all significance when it was destroyed during the Thirty Years' War. In 1838 the Grand Duke of Baden again granted a city charter to Renchen but it again lost the right to call itself a city as a result of the German district reform in 1935. Renchen then received a city charter for the third time in 1950 in recognition of its historic importance.
Renchen's borough of Ulm zu Renchen is known mostly for its Ulmer Bier, a specialty beer brewed only at full moon.
