Bennoschlösschen, Cultural heritage château in Radebeul, Germany.

Bennoschlösschen is a two-storey Renaissance manor house on the Unterberg vineyard slope in Oberlößnitz, Radebeul. It has an almost square plan, a saddle roof with two-zone volute gables and round windows, and a massive buttress with a lean-to roof at the southwest corner. A two-storey flat-roofed annex stands on the north side.

Hans Harrer, chamberlain to Elector August of Saxony, acquired the Hermsdorf estate in 1574 and is regarded as the builder of the Steinernes Haus, already drawn on Matthias Oeder's map around 1580/1600. After Harrer's suicide in 1580 the property passed as an inheritance; in 1620 Hans Harrer auf Ringenhain bought four vineyard plots with the house for 3000 guilders. In the 19th century the house took the name Bennoschlösschen after Bishop Benno of Meissen, though no ownership by the Meissen bishops is documented. From 1992 the owner restored it.

The name Bennohaus or Bennoschlösschen dates from the 19th century, recalling Bishop Benno of Meissen, though no ownership by the Meissen bishops is documented. Writer Karl Julius Hofmann noted in 1851 the four narrow gables in the shape of a bishop's mitre. The building is rented and the vineyards around it are leased to the Hoflößnitz estate.

The house is privately owned and rented out, so it cannot be visited inside; the walled vineyard and the building itself are seen from Bennostraße and Weinbergstraße. The southwest corner shows the large buttress with its lean-to roof, and the north side the two-storey flat-roofed addition. The slopes of the Unterberg rise gently, and the site lies within the protected historic vineyard landscape.

The four gables are said to resemble a bishop's mitre, which is how the name Benno, after Bishop Benno of Meissen, came into use in the 19th century. No ownership by the Meissen bishops is documented; the link rests on the writer Karl Julius Hofmann, who noted the mitre-shaped gables in 1851.
