Schloss Pöchlarn, Renaissance castle in Pöchlarn, Austria.

Schloss Pöchlarn is a Renaissance residence in Pöchlarn with an L-shaped layout and two stories, with the south wing being the oldest part dating to the 13th century. The building developed through several construction phases that document its long transformation.

The site began as a fortified house of the Regensburg bishopric, first documented in 1334 and dated by excavation to the second half of the 13th century. In 1576 Bishop David Kölderer von Burgstall had it rebuilt as a Renaissance castle. After secularisation in 1803 it passed to Bavaria, was auctioned in 1823 to Friedrich Bors von Borsod, and reached the von Tinti family in 1900.

The name Schloss Pöchlarn covers the main building and its outbuildings, including the Schüttkasten, a two-storey granary with a saddle roof between stepped gables. Its neo-baroque window frames date from a remodelling in the second quarter of the 19th century under the Bors von Borsod family. Inside, a barrel-vaulted passage and a two-nave pillar hall survive.

The castle functions as a senior residence and nursing home since 2005 following extensive renovations in 2004, so inside access is limited. Visitors can view the exterior and grounds from outside areas and appreciate the architectural form from public viewpoints.

Archaeological excavations in 2002 uncovered foundations of a Roman fort and medieval walls beneath the current structure. These discoveries reveal the deep historical layers upon which the present building was constructed.
