Neu-Wildon (Ober-Wildon)

The site occupies a wooded summit plateau about 300 metres southeast of Wildon town, roughly 300 metres long and about 80 metres across, with steep slopes to the north and south. The summit was enclosed by a continuous ring wall whose surviving stretches are most evident on the west, east and southeast sides. An artificially cut neck ditch separates the western sector of the castle from the rest of the plateau and survives in part as a hollow way, while an additional artificial ditch follows the eastern edge of the plateau, shaping the approach routes across the hilltop.

The western approach is defended by two successive wall lines. A sixteenth-century blocking wall built with interlaced, net-like stonework adjoins the western ditch, terminates to the north in a small rounded defensive projection and carries a semicircular gate tower that projected outward and served as the access point into the inner area. An older ring wall, built in thin squared ashlar masonry about 0.9 metre thick and dated to the early thirteenth century, once contained the original western gate; fragments of this early wall appear on the western, southeastern and eastern flanks of the plateau. In the eastern sector a gate chamber was added in the sixteenth or seventeenth century, and an outer courtyard lay before the north wall, entered through a gate in that same northern wall.

At the heart of the complex the main castle clusters around a small courtyard that contains a well or cistern and preserves the stump of a round pillar; a nineteenth- and early twentieth-century observer recorded the ring of a cistern in the courtyard. The north and south main walls show masonry from the early thirteenth century. The southern wall displays ashlar courses that were reinforced in the first half of the sixteenth century by a substantial protective outer wall whose stonework matches the western blocking wall in style, indicating contemporary repair or strengthening. The northern wall survives to its original height in places and carries a projecting, console-supported oriel that functioned as a smoke outlet, together with a stone outlet that served a kitchen located behind that wall.

A later building was added against the original outer wall in the northwest, constructed in irregular rubble with brick elements and dated to the sixteenth century; it preserves rectangular window openings with shallow-arched surrounds. In the western bailey stand the remains of a freestanding chapel, probably built in the sixteenth century on older foundations and originally covered by a barrel vault; fragments of Gothic buttressing survive and a carved coat of arms dated 1520 commemorates Ulrich von Leysser. West of the chapel lies a large mass of collapsed masonry that is interpreted as the remains of a tower depicted in a 1681 engraving.

Archaeological work at the site has included surface collection and recording. Surface finds gathered in 2011 are datable to the thirteenth or fourteenth through the sixteenth or seventeenth centuries, and the ruins and immediate area were cleared of trees and subjected to a digital survey as part of a preservation project in 2019–2020. Today the complex stands as a ruined hill castle composed of multiple masonry phases, with the surviving walls, vaulted fragments and carved stonework giving a layered picture of medieval construction, later repair and early modern conversion.
