Haseldorf manor, Manor house in Haseldorf, Germany.

Haseldorf manor is a neoclassical manor house in Haseldorf, Schleswig-Holstein, with a white symmetrical facade, columns, and a triangular gable above the main entrance. It is listed as a heritage monument in Schleswig-Holstein and sits within a landscaped park.

The present manor was designed and built in 1804 by the Danish royal master builder Christian Frederik Hansen for Hans Heinrich von Friccius-Schilden. The estate itself traces back to a castle built by the Archbishop of Bremen in 1184, destroyed in 1258, rebuilt in 1317 and ruined by Wallenstein's troops in the Thirty Years' War. The von Schilden family, owners since 1731, commissioned the new house.

The park holds an old, species-rich stand of trees, with an avenue running from the north toward the main house. At its eastern end, hidden behind tall trees, stands the family mausoleum built in 1884; the moat and rampart of an earlier castle survive there. At the western end is the late-Romanesque church of St. Gabriel, where the poet-prince Emil von Schoenaich-Carolath is buried.

The manor is in the small village of Haseldorf and can be reached by regional road, with parking available close to the grounds. The park paths can be uneven in wet weather, so sturdy footwear is a good idea.

The 1884 family mausoleum stands at the park's eastern end, hidden behind tall trees on the site of an earlier castle; its moat and rampart are still visible in the ground. The neo-Gothic burial chapel is easy to miss from the main allée.
