NDP: Conservation Reliefs and Statues

A damage diagnosis was carried out on the reliefs and on the statues including the heads with the help of ultrasonic measurements.

The risk assessment made clear that the reliefs at the West-Terrace were in total decay. Every year pieces of the sandstone delaminated. The famous Lion Horoscope had become a shadow of the original relief as it was first found.

Limited and reversible conservation methods were tested and carried out in part. The damaged and delaminating reliefs were treated.
