The city wall was first mentioned in 1265. Several gate towers served to monitor the entrances. Only the stork tower, also called the white tower, has been preserved. Its three lower floors show that it was originally open to the city. In 1788 it was rebuilt because the roof was in danger of collapsing. It was then demolished to city wall height. During the Hambach Festival in 1832, the lawyer and landowner Johann Jakob Schoppmann entertained opposition members in the tower. End of the 19th century. At the end of the 19th century, the building was converted into a telegraph tower. It was raised by two storeys and the former embrasures were replaced by windows. According to historian Paul Habermehl, the city bought the tower in 1988 to make the platform accessible. But it never happened. The renovation carried out in 1999 and 2000 mainly related to the exterior facade. The flat roof was replaced by a pointed roof. The city invested 200,000 marks at the time. The Stork Tower takes its name from a Merian engraving of 1619, which shows it with a stork’s nest.
