Gloomy vaulted passagewaysThe casemates
A sought-after but seldom found treasure: the casemates of Heidelberg Castle. From the outside, these hidden 16th-century passageways are often only detectable because of small embrasures.
Heidelberg Castle
Truly romantic: the world-famous ruins
Pointed casemates surround the buildings.
Defensive fortress
Prince-Elector Ludwig V expanded Heidelberg Castle into a fortress during the first half of the 16th century. In addition to massive towers and thick defensive walls, casemates were also installed. These above-ground vaulted passageways offered protection from enemy artillery fire. Troops could also move undetected between fortifications around the castle.
Vault of the north casemate.
The north casemate
The north casemate, built in 1535, runs between the Thick Tower to the west and the Ladies’ Wing to the east. It cordons off the stag pit and the Artillery Garden from the town. In the early 17th century, the north casemate served as a dado, or pedestal, for the English Wing. Tours include a short passageway through this old fortification.
Hiding between the powder tower and a supporting wall: the barrier.
Eastern fortifications
Casemates in front of the castle have also been preserved on the east side, between the Apothecary's Tower and the powder tower. They were constructed in the second half of the 16th century. The interior casemate passageway between the powder tower and the retaining wall for the terrace was an important element of the castle's defense. This casemate protected the castle entrance from the Frisian valley.
In the summer, the Heidelberg Castle Service Center offers special tours through the casemates.
