Stock Photo - 12 September 2023, Saxony, Meißen: Restorers stand on scaffolding behind the high altar in Meissen Cathedral and mount medieval stained glass windows. Over the past four weeks, the valuable stained glass windows of Meissen Cathedral have been scientifically researched and conserved as part of an international project. The stained glass windows of Meissen Cathedral, built in the 13th century, are considered to be the oldest preserved in Saxony and, according to the scientists, are of great cultural importance far beyond. Nineteen panels in the chancel window date from around 1270, twelve in the windows of the All Saints' Chapel from the 14th century. Photo: Robert Michael/dpa. - Meißen/Saxony/Germany
