Grenna Museum, Polar history museum in Gränna, Sweden

Grenna Museum – Polarcenter is a museum in Gränna with two sites. Its Polarcenter section displays finds from S. A. Andrée's Arctic balloon expedition, while the local-history section occupies Franckska gården, Gränna's oldest house, dating from the mid-1600s. Andrée's childhood home stands across Brahegatan, opposite the museum.

Grenna Museum is built around Salomon August Andrée, the engineer from Gränna who in 1897 set out for the North Pole in the hydrogen balloon Örnen. The expedition failed and its remains were not found until 1930. Finds from the attempt are displayed in the Polarcenter, and Andrée's childhood home stands across Brahegatan, opposite the museum.

The local-history section in Franckska gården, Gränna's oldest house from the mid-1600s, presents the town's polkagris candy-making and Amalia Erikson, known as the mother of the polkagris. The exhibition also covers Gränna through different decades and includes portraits of local figures.

The building sits in the town center and is easy to reach on foot, with clear signs for both exhibition sections. Plan for two to three hours to explore both areas comfortably.

A dedicated computer station allows visitors to connect with ongoing Arctic research projects and view current expedition data. This connection merges historical exploration with present-day polar science in one space.
