Bertoldsbrunnen, Fountain in Altstadt, Freiburg, Germany

Bertoldsbrunnen is a fountain featuring an abstract bronze knight figure mounted on a limestone pedestal at the intersection of Kaiser-Joseph-Strasse and Salzstrasse. Water flows through a shallow basin surrounding the statue, which is illuminated by integrated LED lighting.

The original fountain was built in 1807 and destroyed during a British air raid in 1944. The current design was rebuilt in 1965 according to plans by artist Nikolaus Röslmeir.

The fountain's name refers to Berthold III of Zähringen, Freiburg's founder, though the 1965 monument honours the whole Zähringen line. Latin inscriptions on the pedestal name Karl Friedrich of Baden, Berthold III, Conrad I and Albert of Austria, and the base reads "Den Herzögen von Zähringen, Gründern und Herren von Freiburg im Breisgau". The tram stop of the same name makes the crossing a habitual meeting point.

The monument stands in the middle of the tram junction, where four of Freiburg's five tram lines stop at the Bertoldsbrunnen halt. The surrounding streets were closed to private cars in 1973, so the crossing is reached on foot or by tram. The basin is set into the ground, letting visitors walk up to the pedestal from all sides.

The 1965 rider was cast in bronze after the city council made public donations a condition in February 1958; the monument cost 120,000 DM. Sculptor Hugo Knittel had offered a free replica of the lost 1807 Berthold statue, but Joseph Schlippe rejected it in favour of a new design. The medieval seal image of a mounted duke served as the model for the rider.
