The Heinrichstein is a rugged rock massif with a viewpoint on the western slope of the Saale valley in the upper area of the Bleilochtalsperre. The height of the viewpoint is given as 515 meters above sea level; It rises about 100 meters above the water level of the dam. Since it is on the outside of an arc of the Saale, it offers a good view of a large part of the dam.
The Heinrichstein lies on the corridor of the former community Schönbrunn, which is now part of the city of Saalburg-Ebersdorf. Hiking trails to Heinrichstein lead from Schönbrunn over the "Green Donkey" and from Ebersdorf over the "Pohlighaus", each with a length of about three kilometers.
It can be assumed that the Heinrichstein bears its name after the Lords of Reuss, who all had the nickname Heinrich since the 12th century. An older name is Stuhfels, which refers to the damming of the river on the Prallhang; the neighboring slope is still called Stuhleite today.
The first written mention as Heinrichstein was in a handwritten chronicle of Ebersdorf, in which around 1740 there is talk of "love feasts on the Heinrichstein", which were held by the Brethren in Ebersdorf and where, in addition to religious acts, people ate and drank together . It was drawn on a map for the first time in 1757.
The beauty of the view from Heinrichstein, even before the Bleilochtalsperre was dammed, was praised by Ludwig Ganghofer in two poems in 1912. Julius Sturm also wrote poems about the Heinrichstein, one of which is posted in the refuge at the lookout point.
The area around the Heinrichstein is a nature reserve.
