The idea of ​​a new district in the northeastern Hardtwald came in the 1950s and 1960s, as the population of Karlsruhe and the resulting demand for living space rose sharply. The groundbreaking ceremony took place in 1957 and the first residents moved in in 1958. This is how today's forest town came into being. The Waldstadt can be reached with line four of the Karlsruhe city railway and ended at the “Jägerhaus”; today the line extends to the Europaviertel.

The development brought new housing options for single-family and terraced houses, new schools of all kinds - including the European School and the Waldorf School. In addition to these, various sports facilities and the fan pool were created. The forest town was designed for 25,000 residents, currently around 12,000. A settlement in the Blankenloch district was briefly planned for more than 35,000 people. The hoped-for population growth did not materialize and fell significantly, so the planned apartments were of no further use. It took around 30 years for the forest city to get its own center. The forest town center that was built has firmly developed into a popular meeting place in the district and is now an indispensable part of the city. Despite the district's somewhat difficult history, the residents appreciate their forest city. A theater serves as a tourist attraction: the Owls. The Käuze resides on Königsberger Straße and was founded by former track and field athlete “Charly” Kaufmann.
