Ruine Oberwallsee

The ruin occupies a partly wooded hilltop above the Pesenbach valley at 365 metres above sea level, with a built footprint of about 4,300 square metres divided between a high inner enclosure of roughly 1,443 square metres and a semicircular outer enclosure of about 2,857 square metres. The high enclosure was laid out as a ring of buildings around an inner courtyard rather than around a single, freestanding defensive tower, reflecting its combined residential and representative purpose.

The principal residential block, the palas, rises in four storeys and sits on a ground plan that changes direction twice. On the ground level there is a large hall-like room that later received a brick vault, while an original transverse or belt-arch of dressed stone survives and once carried the timber ceiling. The upper floor contained the main reception or dining chamber, which opened directly into the gallery of the chapel and onto a forecourt terrace, indicating close physical and functional links between the living quarters and the chapel.

The chapel is a two-bay space ending in three small apses, covered by a ribbed cross vault that springs from slender columnar supports. Its interior was fitted with Baroque furnishings during the eighteenth century. Both the chapel and the residential block retain an encircling cornice and richly profiled bases beneath projecting wall elements; these carved and moulded details underline the building’s status as a high-quality noble residence.

The outer enclosure lies to the south and west of the main group and is enclosed by a continuous wall that in places acts as a retaining face for the terrace. The outer works were closed on the north and east by gate buildings. The northern or rear gatehouse remains standing, while the front gatehouse at the main approach collapsed during the mid-nineteenth century. Agricultural structures were arranged along the ring wall of the outer court; one of these farm buildings, historically the manorial farm, later became a smallholding and today serves as a residential house.

Today the ensemble survives as a ruin with significant fragments of its fabric in situ. The rear gatehouse, portions of the palas including the historic arch and hall, and the chapel structure remain identifiable. Other parts of the complex show collapse or long-term abandonment, and conservation work has been undertaken on surviving elements since the late 1950s.
