Lauterberg, Artificial mountain in Stadtgarten, Karlsruhe, Germany

Lauterberg is an artificial hill in the Karlsruhe Stadtgarten, heaped up from 1889 to 1893 from the spoil of two lakes dug in the surrounding ground. It rises about 40 metres above the city centre and holds a riveted wrought-iron water tank of 3,200 cubic metres inside. A viewing platform on the summit is reached by a bird conservation trail.

The mountain was built between 1889 and 1893 and originally contained a water reservoir that supplied Karlsruhe until 1967. After that, the basin was filled with concrete for safety reasons.

The hill is named after Wilhelm Florentin Lauter, Karlsruhe's mayor from 1870 to 1892, under whom construction began; he died before the project was finished. The name therefore ties the mound to the city administration that ordered it, not to a natural feature.

The summit platform is reached via a bird conservation trail (Vogelschutzlehrpfad) laid out on the hill. The hill rises about 40 metres above the Karlsruhe city centre, so the climb is short. The former reservoir inside is sealed with concrete and cannot be visited.

The hill was raised with material dug out for two lakes in the surrounding grounds, not from a station square, and no 1913 date applies. The summit platform is reached along a bird conservation trail, and until 1958 a sham castle ruin with a lookout tower stood there, built from stone remains of Rastatt fortress.
