Karlstor

Karlstor stands at the eastern end of Heidelberg’s Old Town as a classicist triumphal arch. Its Roman-inspired form marks the historic boundary and presents a substantial passageway through the city’s former fortifications. Wheelchair users can access the architectural landmark.

Construction began in 1775 and finished in 1781, replacing the earlier Inner Upper Gate, or Jakobspforte. Heidelberg’s citizens proposed the project as a tribute to Elector Karl Theodor, although residents complained about its high cost. Nicolas de Pigage designed the structure by combining elements from three proposals, following the elector’s suggestion. Peter Simon Lamine created the sculptural decoration, which connects the gate with Karl Theodor and his court.

Four Palatine lions crown the central section and reference the region’s heraldic symbols. The eastern side shows the elector’s coat of arms between two lions, while the western side presents portraits of Karl Theodor and his wife beneath a princely hat. A trophy of arms and another Palatine coat of arms rise above the dedication inscription, while the unfinished original plans remain part of its history.
