The Gerhart Hauptmann House Municipal Museum is located in Jagniątków (formerly Agnetendorf), which was incorporated into the city of Jelenia Góra in 1997.

The museum is housed in the former home of the German writer and 1912 Nobel Prize winner.

The historic building, set on a granite rock called Łąkowy Kamień (Wiesenstein), is surrounded by a park covering an area of approximately 1.6 hectares. It was originally designed as a villa with a panoramic view of the Karkonosze Mountains. The writer lived here from 1901 until his death in 1946. The residence served as a refuge for the writer and his family between longer stays on the island of Hiddensee and in Italy, among other places.

For almost half a century, Willa Łąkowy Kamień was also a center of cultural and social life for many artists, writers, intellectuals, and artists from the Karkonosze and Berlin circles, as well as a place famous for its valuable art collections.

After the writer’s death, many ideas for the use of the building emerged. Ultimately, the “Warszawianka” Children’s Holiday Home was established here, which until mid-1998 welcomed children and young people for holiday stays and green schools. In 1989, following a joint statement by German Chancellor Helmut Kohl and Polish Prime Minister Tadeusz Mazowiecki, it was decided to establish a museum dedicated to the Nobel Prize winner at this location. After municipalization, thanks to the support of the Federal Government of Germany and the Foundation for Polish-German Cooperation, the villa underwent thorough renovation and restoration and ultimately changed its purpose. On September 1, 2001, during a ceremony attended by the prime ministers of Poland and Saxony, the Gerhart Hauptmann House was officially opened as a cultural institution of the City of Jelenia Góra. The intention to turn the facility into a museum was only realized four years later, and since May 1, 2005, the institution has been operating as the Gerhart Hauptmann House Municipal Museum in Jelenia Góra.

The museum offers visitors seven exhibition rooms closely connected with the work of Gerhart Hauptmann. Visitors can see, among other things, the writer’s study, the former library, the former dining room, and a room entirely decorated with polychrome paintings created in 1922 by J. M. Avenarius, known as the Paradise Hall due to the subject matter of the paintings.
