Castle Dietldorf
1390 in Niederdietldorf, today's Dietldorf, a Schienhammer, 1457 in Oberdietldorf, today's Pettenhof, a sheet metal hammer is mentioned. Both were originally owned by the Scottish monastery of St. Jakob in Regensburg. Towards the end of the hammer operation, a weapon hammer was operated here until 1849.
The palace is a three-storey hipped roof building in the style of the Italian late Renaissance, designed by a builder whom Friedrich Eberhard Tänzl had recruited from Italy, and erected between 1700 and 1705. A Veronese villa allegedly served as the model for the building, which is unusual for the Upper Palatinate. The baroque portal is marked "1700", it shows the alliance coat of arms of Friedrich Eberhart Freiherr von Tänzl and his wife Maria Theresia von Altenheim.
The courtyard wall is made of partially plastered quarry stone and brick masonry, which dates from the 18th century. The former adjoining building of the palace "Beim Schreiner" is an elongated, three-story half-hipped building with a two-story lean-to roof extension to the east; its core dates back to the 17th century, with a southern extension dating from after 1920.
The hammer mill ceased operations in 1840. The hydroelectric power plants at the castle were modernized in 2012 and are used to generate electricity.
The castle is owned by the Counts of Spreti, an old noble family of counts from Ravenna/Italy, which has been based in Bavaria since 1701. Schloss Dietldorf is inhabited privately and is not open to the public. The castle park is occasionally made accessible to a broader public through cultural events.
