The Natural History Museum (Göteborgs naturhistoriska museum) is itself something of a glimpse of history, since it’s the oldest museum in Gothenburg, founded in 1833. The museum hosts a huge collection of over 10 million animals of all sizes. But the main attraction is the “Malm Whale”—a large blue whale named after Mr. A.W. Malm, who was working at the museum in October 1865 when a blue whale got stuck in the Askim Bay. It was killed by locals and transported to one of the shipyards in the Port of Gothenburg, where the skin was removed and a large wooden skeleton was created to stretch the skin over. It was then transported to the museum. The interior of the whale (the skin stretched over the skeleton) was decorated with a sofa and printed wallpaper. You can even enter through the mouth, though it's not always open.
