Lenné Park Hoppegarten

The influential landscape architect Peter Joseph Lenné also left his mark on the former estate park in Hoppegarten. The park, now named after him, was laid out in 1821 according to his plans. In addition to the park itself, he also incorporated the farmyards, kitchen gardens, and wetlands located beyond the avenue into his design. In front of Hackesche Palace, opposite the estate buildings, the grounds, sparsely planted with trees and shrubs, slope gently downwards. Almost always, these are dense, often bulging, long groups of trees and shrubs, which, contrary to the otherwise common use of grove-like plantings of individual trees, make the park appear almost bare. There are numerous sightlines, and the palace is not the sole focal point. The original layout of the park landscape, with its paths, waterways, and picturesque groupings of trees and shrubs, is still partially discernible.

In 1850, Carl Heinrich von Treskow acquired the castle and park from Countess Hacke, the great-granddaughter of Samuel von Marshall. Heinrich von Treskow was known as the builder of Dahlwitz Palace and co-founder of the Hoppegarten racecourse. In 1855/56, the Berlin architect Friedrich Hitzig, one of the most important architects of Schinkel's generation, built a palatial manor house for Treskow in the style of the Potsdam tower villas, which were frequently built in Berlin and Brandenburg in the mid-19th century. In the second half of the 19th century, the tower was raised and an extension was added to the north side.

Since 2004, the palace and park had been owned by Brandenburgische Schlösser GmbH. The listed palace was sold to a private investor. The park was restored to its original design in 2005 and remains open to the public at all times.
