Because of its importance as a centre of culture during the Weimar Classicism movement of the late 18th and early 19th centuries, the Tiefurt House was inscribed on the UNESCO World Heritage List in 1998 as part of the Classical Weimar site.

Four years later their mother selected it as her summer seat during a long absence of the prince.

She and her two servants occupied the upper floor, with her courtier, Luise von Göchhausen, in the auxiliary building.

For around 25 years the castle was Anna Amalia's favourite residence and the centre of a circle of poets, as part of Weimar Classicism.

On the nearby meadow was a landscape garden in the English style, also open to the public.
