Schloss, Manor house in Mammendorf, Germany.

Schloss is a manor house in Mammendorf with white walls, symmetrical windows, and a steep roof displaying typical Bavarian architectural elements and timber details. The building remains surrounded by its original estate grounds with adjacent gardens that preserve the historical spatial arrangement of a country residence.

A medieval fortress stood here before the present building: Duke Ludwig the Bearded acquired it around 1403/05 and expanded it into a "Veste", which Bavarian War troops destroyed in 1422. After Duchess Anna, widow of Duke Albrecht III, died here on 9 October 1474, the estate passed to court chancellor Christoph Elsenheimer in 1585; Swedish troops devastated it in 1632. The present palace was built around 1752 near the old fortress, and the Lotzbeck barons, who bought it in 1826, had Jean Baptiste Métivier give it a Neoclassical remodelling in 1840/48.

The name Nannhofen comes from the local noble family, the Nannhofer, who held the estate as Freising ministerials; in 1305 Wernhart von Nannhofen sold the Sedlhof, two farms and the village court to the knight Ott der Eisenhofer. From 1585 the estate was a ducal Hofmark under Bavarian chancellor Christoph Elsenheimer, and in 1826 the Freiherren von Lotzbeck acquired it with the patrimonial court, abolished in 1848. The castle is privately owned and not open to the public; visitors see it from outside, 60 m east of the St. Peter und Paul chapel.

Schloss Nannhofen stands in the hamlet of Nannhofen, about 60 m east of the branch church of St. Peter and Paul, in the municipality of Mammendorf. The building is privately owned and not open to the public, so it can only be viewed from outside. The baroque west facade with its tower faces the street side.

The castle stands on a site where medieval and early modern remains of its predecessor fortress, the "Veste" and "Neue Veste", are recorded as an archaeological monument (D-1-7733-0005). The present building was raised around 1752, only 60 m east of the parish church of St. Peter and Paul.
