Reinerhof, Heritage building in Sackstraße, Graz, Austria.

The Reinerhof is a hook-shaped building between Schloßbergplatz and the former Palais Khuenburg, with a core from the 15th century and Biedermeier facades of 1839–1840 by Georg Hauberisser the Elder. Three terracotta reliefs of Spring, Summer and Autumn decorate its north side. In the ground floor of the east wing a small late-Gothic hall stands on a single central pillar that once carried painted coats of arms.

The structure has existed since before 1164, making it among the oldest surviving buildings in the Styrian capital. This long history provides evidence of how the city developed and changed across multiple centuries.

The building holds protected monument status with designation number 44333, demonstrating the preservation of Austrian architectural heritage through centuries.

The Reinerhof stands between Schloßbergplatz and the former Palais Khuenburg, now the Graz Museum, on Sackstraße. The ground floor of the longer north wing, partly below the level of Schloßbergplatz, holds shops and two restaurants; the flats above are reached by a small external stair and a door on the north facade.

The late-Gothic hall in the east wing has a single central pillar that once carried painted coats of arms; such one-pillar rooms are usually limited to the 13th century. In 1887/88 Johann Puch worked as foreman in the bicycle department of the sewing-machine dealer Luchscheider here, and a lathe from that time was found when the hall was cleared around 1997/98.
