It is presumed that the Battenberg castle was constructed by Count Frederick III of Leiningen (d. 1287), and it remained a possession of the House of Leiningen - until 1689, when it was destroyed during the War of the Palatine Succession by French troops. Together with Neuleiningen Castle, on the opposite hillside 1,400 metres to the north, it controlled access to the Eckbach valley.
On three sides the outer walls of the castle follow the edge of the steep-sided hill spur. The wall on the fourth side was protected by a moat, now completely filled in. Surviving structures include: the outer walls, a gate tower on the western side near the northwest corner of the site, a battery tower with embrasure in the centre of the south side, and the vaulted cellar and foundations of a large dwelling. Attached to this is a staircase tower, erected in the 16th century, which is still standing.
The ruins are in private ownership but there is limited public access.References:
Redipuglia is the largest Italian Military Sacrarium. It rises up on the western front of the Monte Sei Busi, which, in the First World War was bitterly fought after because, although it was not very high, from its summit it allowed an ample range of access from the West to the first steps of the Karstic table area.
The monumental staircase on which the remains of one hundred thousand fallen soldiers are lined up and which has at its base the monolith of the Duke of Aosta, who was the commanding officer of the third Brigade, and gives an image of a military grouping in the field of a Great Unity with its Commanding Officer at the front. The mortal remains of 100,187 fallen soldiers lie here, 39,857 of them identified and 60,330 unknown.
