archaeological site on the island of Bjxc3xb6rkxc3xb6 in Sweden
Birka listenxc2xa0(helpxc2xb7info) (Birca in medieval sources), on the island of Bjxc3xb6rkxc3xb6 (literally: "Birch Island") in present-day Sweden, was an important Viking Age trading center which handled goods from Scandinavia and Finland as well as Central and Eastern Europe and the Orient.
The archaeological sites of Birka and Hovgxc3xa5rden, on the neighbouring island of Adelsxc3xb6, make up an archaeological complex which illustrates the elaborate trading networks of Viking Scandinavia and their influence on the subsequent history of Europe.
[citation needed] The Baltic island of Gotland was also in a better strategic position for Russian-Byzantine trade, and was gaining eminence as a mercantile stronghold.
Furthermore we have been told that there are many more islands in that sea, one of which is called the Great Estland (Aestland) -- And this island is told to be quite close to the Woman Land (terrae feminarum), which[14] is not far (non longe) away from Birka of the Swedes.
However, the island of Bjxc3xb6rkxc3xb6 was first claimed to have been Birka already about 1450 in the so-called "Chronicle of Sweden" (Prosaiska krxc3xb6nikan):
Birka was on an island in Lake Mxc3xa4laren (mxc3xa4lar) that is called Bjxc3xb6rkxc3xb6 (birkxc3xb6xc3xb6).
In the late 19th century, Hjalmar Stolpe, an entomologist by education, arrived on Bjxc3xb6rkxc3xb6 to study fossilized insects found in amber on the island.
Stolpe found very large amounts of amber on the island, which is unusual since amber is not normally found in lake Mxc3xa4laren.
Stolpe speculated that the island may have been an important trading post, prompting him to conduct a series of archeological excavations between 1871 and 1895.
The excavations soon indicated that a major settlement had been located on the island and eventually Stolpe spent two decades excavating the island.
An adjacent island holds the remains of Hovgxc3xa5rden, an estate which housed the King's retinue during visits.
[21] Its administrative center was supposedly located outside of the settlement itself, on the nearby island of Adelsxc3xb6.
Bjxc3xb6rkxc3xb6 is today mainly agricultural, and shipping lines carry tourists to the island, where a museum showcases a view of life during the Viking era.
The town of Birka was optimally situated on Bjxc3xb6rkxc3xb6 Island at the convergence of several important waterways.
Its activities were organized and governed from the royal residence at Hovgxc3xa5rden, situated across the strait on the neighbouring island of Adelsxc3xb6.
Identified potential threats and risks to the authenticity of Birka and Hovgxc3xa5rden include environmental hazards such as ground or forest fires, over-fertilisation of farms, shoreline damage from nearby leisure and passenger boat traffic, and transport of hazardous products near the islands; damage to the ground surface by visitors; depopulation of Bjxc3xb6rkxc3xb6 Island; and lack of an archaeological research plan.
