Baltic amber is fossil resin produced by pine trees which grew in Northern Europe about 50 million years ago. The resin was washed out of the forest floor by large rivers and transported south towards the sea. In the course of time the resin was transformed to amber due to processes of polymerisation and oxidation.

Užupis is a neighborhood in Vilnius, the capital of Lithuania, largely located in Vilnius' old town, a UNESCO World Heritage Site. Užupis means "on the other side of the river" in the Lithuanian language and refers to the Vilnia River. The name Vilnius was derived from the Vilnia. The district has been popular with artists for some time, and has been compared to Montmartre in Paris due to its bohemian atmosphere. The district houses art galleries, artists' workshops, and popular cafés. On April Fools Day, 1997, the district declared itself an independent republic (The Republic of Užupis), replete with an army of 12 personnel.
