Schloss Cotta, Heritage castle in Dohma, Germany

Schloss Cotta is a castle in Dohma featuring neo-Renaissance architecture, stone walls, and multiple floors. The building sits on grounds with a park that occupies a substantial portion of the property.

The estate began as a manorial district founded by the Burgraves of Dohna around 1000 and was first documented in 1307 as a Vorwerk. The lords of Kospoth expanded it into a knight's estate in the 16th century. Carl Freiherr von Friesen acquired it in 1661 and had a new castle built next to the church from 1662, while the old manor became a brewery. In 1821 the Leipzig bookseller Gottfried Christoph Härtel bought the estate; from 1833 his daughter Elwine von Leyser had it remodelled in Neoclassical style by Woldemar Hermann. In 1895 Dora von Eschwege rebuilt it in Neo-Renaissance style, adding oriels, decorative gables, turrets and balconies.

The estate's name and history tie it to the village of Cotta, now part of Dohma. In 2011 the castle was used for the filming of the adaptation of Uwe Tellkamp's novel Der Turm. The park north of the building, about three-quarters of a hectare with a small pond, was laid out around 1895.

The castle has stood empty since 1991; renovation plans were never carried out, and only individual rooms were used while the rest was merely maintained. In late 2016 the Dohma council sold it to a Freital property developer for €350,000. It is privately owned, so there is no regular visiting offer; the park with its small pond lies north of the building.

An older building on the property was converted into a brewery during the von Friesen family ownership. This outbuilding shows how the estate served different economic purposes over the centuries.
