The Amber Museum-Gallery on Šv. Mykolo Street displays a collection of Baltic amber with inclusions — insects, plant fragments, and other organic material trapped in fossil resin 40–50 million years ago. Baltic amber is scientifically significant as a preservative of Eocene-era organisms, and the pieces on display here include some of the more unusual inclusions: spiders, ants, mushrooms, lizard tails.
Lithuania's amber coast and the Baltic Sea produce amber in quantities found nowhere else; the Curonian Spit and Palanga are the main sources. The museum explains both the geology and the cultural history of amber use, from Neolithic Baltic peoples to the medieval amber trade routes. There is a jewellery workshop and shop attached. Šv. Mykolo St. 8. Open daily 10:00–19:00.
