Sachsenstein, Memorial stone in Breitungen, Germany.

Sachsenstein is a memorial of hewn sandstone, made of a main stone with a separate curved top stone, set within a low enclosure of laid sandstone blocks. It stands on the summit plateau of the Pleß beside the Pleß tower, where it was re-erected on a new foundation in 2008.

Duke Ernst Ludwig I of Sachsen-Meiningen had the stone erected in 1722 after his hunter and gun-bearer Johannes Sachs was fatally shot on 6 June 1722 near the "Großen Balz" by the "Entenpfütze". Officially a stray shot, the death followed rumours of murder: Sachs had been the only witness besides the duke when the duke's hunting master's wife died. The stone was moved in 1981 and again in 2008 to the Pleß summit.

The stone carries carved inscriptions on its front and rear faces, renewed in 1909 by order of the forestry administration. The text commemorates Johannes Sachs, the ducal hunter and gun-bearer born on 3 May 1700 and killed on 6 June 1722. The story was later retold by Ludwig Wucke in his novella Der Jägerstein, found after his death in 1883 and first published in 1905.

The stone now stands on the summit plateau of the Pleß beside the newer Pleß tower, where it was set on a new foundation and handed over to the public on 3 October 2008. Marked hiking trails lead up the mountain; the climb is steep, so allow time and wear sturdy shoes.

The curved capstone went missing for a time after repeated vandalism at the 1981 site near the Seeblick inn, where the stone stood in permanent shade and never dried out. The Rhönklub Breitungen restored it in 2008 for €5,000 and placed it beside the new Pleß tower, unveiled on 3 October 2008.
