Burg Henneberg

Description

On the bank of the Alster by the Poppenbüttel lock in Hamburg-Poppenbüttel lies Burg Henneberg, also called the Alsterschlösschen. The structure is an artificially created ruin and is a reduced-scale replica of Burg Henneberg in southern Thuringia at a scale of 1:4.

The origins of the ensemble date to the late 19th century: in 1875 a member of the Henneberg family acquired the site of a former clay pit and had the Marienhof park and the castle ruin laid out there. Between 1884 and 1887 the complex was created in the then-popular neo-Gothic style as a representative feature of bourgeois residences. The Marienhof park covers about 3.5 hectares and was laid out as an English landscape garden with exotic woody plants from Europe, North America, China and Japan; parts of it have survived to the present day.

For the appearance an artificial castle mound of around 15 metres in height was heaped up. The complex includes a main building with a 12-metre-high tower, a small secondary turret and a terrace-like southern annex. Inside there is a room referred to as the "Rittersaal" with a gallery, a castle chamber and the stairway to the tower; a spiral staircase leads to the viewing platform, whose unobstructed view of Hamburg’s church towers is now limited by tall trees. Access is via an open staircase, and artificial "cracks" were applied to the masonry to create an aged impression.

The castle served the Henneberg family as an archive and later was used for various purposes; after the dissolution of the agricultural estate rooms were used at times by a Liedertafel. In 1942 part of the site passed into municipal ownership.

In the following decades the ruin fell into disrepair; in 1988 there was a risk of collapse, and in 1990 the building was acquired by a private buyer who undertook to carry out restoration. In 1991 it was entered on the monument register as "Burgruine Henneberg mit künstlicher Topografie, Typ Folly (Nachbau einer Burgruine), Marienhof 8."

After further changes of ownership, use passed in 2014 to the non-profit Stiftung Burg Henneberg, which aims at preservation and cultural use and for the first time made the building more accessible to the public. Since 2021 the city has permitted commercial use; the property has been up for sale again since 2024, with the possibilities for use considered limited.
