Castle Afing

The remains occupy a narrow rock spur that projects toward the Sarner Gorge and falls away steeply on three sides. Masonry survives on two small rock heads close to the saddle at the western end of the spur, and the surviving stonework rises to about two metres in places. The construction uses Bozner quartz porphyry, and the workmanship varies across the visible sections of wall.

On the northern, slightly higher rock head a roughly rectangular building footprint is preserved, measuring approximately twelve by eight metres, accompanied by several fragments of mortar‑bonded wall. This cluster of walls has been interpreted as the main structural block of the complex and has been equated with the documentary references to Castle Afing. The masonry here remains in situ and stands visibly above the rock platform.

The southern rock head contains far fewer traces, with only scattered wall fragments reported and unstable sections threatened by slippage. On that same southern head a worked area has been identified as a possible smelting location; observers suggested it may have functioned as a wind‑furnace for metal processing, a feature interpreted as a special‑purpose installation rather than domestic accommodation.

A surrounding forework was reported in early reports of the ruin, indicating an outer defensive or approach feature tied to the western access. Measurements made during mapping work estimated the total preserved masonry at well over one hundred cubic metres. Today the remains are fragmentary and confined to the two rock prominences, with collapsed and slipping sections noted and no extensive standing buildings beyond the low rubble walls and the rectangular foundation on the northern head.
