Feuersee

Lake of Fire
The Feuersee, which surrounds the Johanneskirche from three sides, was created in 1701 in a triangular form as Löscherasserteich. During the construction of the Johanneskirche, the lake was restored to its present form. The south shore of the lake was redesigned in 2016 with new seating. The lake is home to many aquatic turtles that have been abandoned there and have been multiplying ever since. The lake is also used for breeding carp and pike.

... in summer you can observe numerous turtles from the shore. There are two theories about the origin: One says that it would be surplus turtles from the Wilhelma, which would be collected again in the winter. The other suspects 'overhangs' from domestic aquariums ...

The lake was, as its name suggests, actually created in 1701 for firefighting. Today he likes to be used for RC boat races or skating.
The lake is supplied by springs in Kaltental with water flowing through the Reinsburgstollen under the Schwabtunnel to the lake of fire.
Unfortunately, many people use the lake as a rubbish dump, so the bicycles, snowboards and shopping trolleys as well as car batteries have been removed due to the few expensive cleaning operations that have taken place so far. In hot summers, the lake was already an odor nuisance. In 2014, the city invested over € 600,000 and, among other things, renovated the South Bank. East and West banks are to follow.

The Johanneskirche am Feuersee is one of the most beautiful churches in Stuttgart.

There are various events taking place around the lake

The Johanneskirche Stuttgart am Feuersee in the west of Stuttgart is a neo-Gothic church and was built from 1865 to 1876 under the direction of the Württemberg architect Christian von Leins. The building is located in the fire pond at the Feuersee and is an architectural masterpiece. During World War II, the church was badly hit by Allied air raids.
Between 1948 and 1966 the church was rebuilt. The missing top of the Stuttgart Johanneskirche was replaced by a platform with a parapet. It serves as a memorial against war.
The Feuersee in Stuttgart West was artificially created as a water reservoir as early as the 18th century. A local fishing association operates the lake as a breeding ground for fish.
When visiting the west of Stuttgart, you should not miss this sight. Incidentally, the Feuersee Festival also takes place here every year.
