The castle well of the Kyffhäuser Monument is the deepest castle well in the world with a depth of 176 meters. It was driven into the rock between 1130 and 1170 and served to supply water to the castle residents. The water level remains constant at 9 meters, fed by seepage water. Modern camera movements allow visitors to look to the bottom of the well and gain a fascinating insight into medieval engineering. An absolute highlight of a visit to the Kyffhäuser Monument!

The well on the Kyffhäuser is the deepest castle well in the world. The depth is about three times the height of the memorial tower. The well pipe has a diameter of just over 2 meters. The well is fed by seepage water, so it is not groundwater. It is believed that the well was driven into the rock between 1130 and 1170. At that time it served to supply water to the castle residents. A recent analysis has confirmed that the sample taken was of the highest drinking water quality.

The best preserved part of the Kyffhausen Imperial Castle is the lower castle, which was only uncovered in the 1930s and partially rebuilt. It has an almost closed ring wall that is preserved up to a height of 10 metres. In the lower castle, the remains of walls and foundations of residential and commercial buildings from various construction phases of the castle, as well as the stump of the keep, have been uncovered. In the rear part, next to the chapel that was renovated in the 15th century, a second tower, possibly a residential tower, has risen. The lower castle must have already existed in 1118, as there is clear evidence of the destruction that took place in that year. However, it is unlikely that it was founded much earlier than the 12th century.

My absolute highlight. The Kyffhäuser Monument is impressive, but the Lower Castle is charming and not overcrowded, at least outside of the holidays. Very romantic.

It's now 9.50 EU, but that doesn't matter, you don't go here every day. And the monument and the museums and other sights also pay.
