Bellevue Palace, Cultural heritage palace in Kassel, Germany

Bellevue Palace is a three-story, nearly square building with two rear wings facing the garden. Its simple facades are broken only by a slight cornice above the ground floor, and the street front has a balcony above a classical portal. The interior combines rococo and classicism, with a well-preserved classical stairway and a large ground-floor room with pilasters.

Landgrave Karl of Hesse-Kassel commissioned architect Paul du Ry to build this palace in 1714, initially designed as an astronomical observatory. The building later transformed into a royal residence and became an important cultural landmark for the city.

Since November 2025 the Spohr Museum, Literaturhaus Kassel and the Brückner-Kühner foundation have jointly run a public bookcase in the Spohr Museum's exhibition rooms. The building also houses the Spohr Museum itself, and the Literaturhaus uses the Remise hall and the smaller Salon for events.

The palace reopened in September 2023 as the House of Literature and Music, so it is open again after the renovation that began in 2009. It now holds the Spohr Museum on two floors, the Remise hall and Salon run by the Literaturhaus Kassel, and an exhibition room curated by the Brückner-Kühner foundation. It stands at Schöne Aussicht 2, next to the Neue Galerie.

It is the only early 18th-century city palace in Kassel to retain substantial portions of its original exterior. This preservation makes it a rare example of baroque architectural style surviving in the city.
