Brentanohaus Winkel, Cultural heritage monument in Oestrich-Winkel, Germany

Brentanohaus is a former wine estate in Oestrich-Winkel, built in 1751 by Johann Michael Ackermann of Bingen. The main house, outbuildings and garden running down to the Rhine form a protected monument. Curved "A" ornaments of the Ackermann family survive on walls and railings, alongside the Brentano coat of arms. The upper-floor Saal was the centre of house life, next to Goethe's bedroom and study.

The house came into the Brentano family's ownership in 1806, becoming a center of their literary activities. Johann Wolfgang von Goethe visited in 1814 and recorded his impressions of the Rheingau region.

The house carries the Brentano family name and their connection to German Romantic literature. Visitors can walk through rooms where writers and thinkers once gathered.

The house is no longer lived in and opens for guided tours by arrangement; parts of the ground floor are leased as a restaurant. The State Palaces and Gardens of Hesse has managed the property since 2014, and restoration work continues alongside visits to the historic rooms.

The bedroom where Goethe stayed keeps a wallpaper whose bright blues were made with Schweinfurter Grün, a toxic pigment; tests showed the colours barely faded over some 200 years. The oldest book in the surviving library dates from the 16th century and holds a collection of songs.
