Admontbichl castle, Renaissance castle in Obdach, Austria.

Schloss Admontbichl is a Renaissance castle in Obdach with multiple wings arranged around a rectangular courtyard. A hand-drawn well built in 1639 sits within the courtyard and demonstrates the water systems of that era.

The Benedictine Abbey of Admont acquired the estate in 1367 as a landed property and later developed it into a fortified castle. Its current form emerged through renovations and expansions from medieval times into the modern period.

The name Admontbichl recalls the Admont Abbey, which bought the estate as the Mereinhof zu Pichl in 1367. The wall paintings in the summer house are attributed to Veit von Seckau, and the builders and stonemasons recorded at the site include Hans de la Porta, Bernard de Novo and Master Thomas Püchler. Daniel Ritter von Gallenberg, who expanded the castle from 1530, raised grain levies arbitrarily and was known as a "Bauernschinder".

The castle stands on a wooded hill in the Rötsch district of Granitzen, address Rötsch 16, and is reached on foot; only remnants of the ring wall and parts of a masonry ditch survive from the former fortifications. The grounds are privately owned since 2012, so views of the exterior and the surrounding forest are the main option.

The two round corner towers of the north wing were destroyed by a fire in 1748 and never rebuilt, so the present building has only one round corner tower. The 1639 draw well in the small rectangular courtyard survives, and a sundial hangs beside the bay window above the arched gate.
