Twannberg meteorite, Iron meteorite at Natural History Museum of Bern, Switzerland.
The Twannberg meteorite is an iron meteorite housed at the Natural History Museum of Bern that contains roughly 5.1 percent nickel in its composition. Its surface displays an oxidation layer that formed during its time buried in the soil.
The first fragment was discovered in 1984 in a barley field near Twann when plowing exposed the meteoritic material. This marked the beginning of a collection effort that eventually brought nearly 1000 fragments to light across the region.
Local collectors and scientists worked together to recover fragments from the region around Lake Biel after the impact event.
The museum displays several fragments year-round in its permanent exhibition where visitors can examine them closely. The pieces are shown in a climate-controlled setting to ensure their preservation.
This hexahedrite belongs to the rare IIG group and is the only known specimen of its classification ever found in Europe. Its rarity makes it of special interest to meteorite researchers worldwide.
