Tea Temple on the Donnerberg

The temple, popularly known as the tea temple, served Count Ernst zu Münster as a vantage point from which he could show visitors his gardens and properties. Inside was a room with a fireplace, in which Münster celebrated the English custom of drinking tea.

Highlight on the Laves culture path.

In the middle of the 18th century, the buildings in Derneburg were under the rule of Count Ernst zu Münster. Under him, not only was the neglected monastery building rebuilt into today's castle, which was renovated but preserved in its original form, but also some other facilities near the castle were built, including the tea house shown in the attached picture.
He received support from the Hanoverian architect Georg Ludwig Friedrich Laves; The Laves Culture Trail, which you are probably walking on, is named after him.
With the construction of this Greek temple on Donnerberg, which was popularly only called the tea temple, the count or his son created a vantage point over the surrounding area. In the meantime, however, the view is severely restricted by the dense tree vegetation. Furthermore, the temple, which housed a fireplace room inside, was used for the English custom of drinking tea; hence the name.
Today the temple is only visited by the locals and a few hikers and, together with the Derneburg Castle, is owned by an American billionaire.
