Rüppurr, located south of Karlsruhe, was first documented in 1103 as "Rietburg." The name "Rietburg" means "house in the reeds or swamp." References to Upper and Lower Rüppurr, as well as a castle district, are made in 1265, and to a St. Nicholas Chapel in 1351. Rüppurr became Protestant following the division of the Margraviate of Baden-Durlach. The last public execution in Baden took place here in 1834. The opening of the Alb Valley Railway in 1898 definitively accelerated its development into a satellite town of Karlsruhe. At Rüppurr's instigation, it was incorporated into Karlsruhe in 1907, with 2,574 inhabitants and an area of 800 hectares. Construction of the second oldest garden city settlement after Dresden-Hellerau began in the same year. Today, Rüppurr is one of the most sought-after residential areas in Karlsruhe and is known for its peaceful and pleasant living environment. With Herrenalber Straße, the motorway and the passage to the Alb valley, the district has a considerable volume of traffic in the center and thus a downside to the otherwise idyllic surroundings.
