History of Sweden between 12000 BC - 4001 BC
The Pleistocene glaciations scoured the landscape clean and covered much of it in deep quaternary sediments. Therefore no undisputed Early or Middle Palaeolithic sites or finds are known from Sweden. As far as it is currently known, the country's prehistory begins in the Allerød interstadial c. 12,000 BC with Late Palaeolithic hunting camps of the Bromme culture at the edge of the ice in what is now the country's southernmost province. Shortly before the close of the Younger Dryas (c. 9,600 BC), the west coast of Sweden (Bohuslän) was visited by hunter-gatherers from northern Germany. This cultural group is commonly referred to as the Ahrensburgian and were engaged in fishing and sealing along the coast of western Sweden during seasonal rounds from the Continent. Currently, we refer to this group as the Hensbacka culture and, in Norway, as the Fosna culture group. During the late Preboreal period, colonization continued as people move towards the north-east as the ice receded. Archaeological, linguistic and genetic evidence suggests that they arrived first from the south-west and, in time, also from the north-east and met half-way.
An important consequence of de-glaciation was a continual land uplift as the Earth's crust rebounded from the pressure exerted by the ice. This process, which was originally very rapid, continues to this day. It has had the consequence that originally shore-bound sites along much of Sweden's coast are sorted chronologically by elevation. Around the country's capital, for instance, the earliest seal-hunter sites are now on inland mountain tops, and they grow progressively later as one moves downhill toward the sea.
The Late Palaeolithic gave way to the first phase of the Mesolithic in c. 9600 BC. This age, divided into the Maglemosian, Kongemosian and Ertebølle Periods, was characterised by small bands of hunter-gatherer-fishers with a microlithic flint technology. Where flint was not readily available, quartz and slate were used. In the later Ertebølle, semi-permanent fishing settlements with pottery and large inhumation cemeteries appeared.
The Palace of the Grand Dukes of Lithuania was built originally in the 15th century for the rulers of the Grand Duchy of Lithuania. The Royal Palace in the Lower Castle evolved over the years and prospered during the 16th and mid-17th centuries. For four centuries the palace was the political, administrative and cultural center of the Grand Duchy of Lithuania.
Soon after the Grand Duchy of Lithuania was incorporated into Tsarist Russia, Tsarist officials ordered the demolition of the remaining sections of the Royal Palace. The Palace was almost completely demolished in 1801, the bricks and stones were sold, and the site was bowered. Only a small portion of the walls up to the second floor survived, that were sold to a Jewish merchant Abraham Schlossberg around 1800 who incorporated them into his residential house. After the 1831 uprising, the czarist government expelled Schlossberg and took over the building as it was building a fortress beside it. Before the Second World War it was the office of the Lithuanian Army, during the World War II it was the office of the German Army, and after World War II it was used by Soviet security structures and later transformed into the Palace of Pioneers. Fragments of Schlossberg's house have become part of the Eastern Wing of the restored Royal Palace.
A new palace has been under construction since 2002 on the site of the original building. The Royal Palace was officially opened during the celebration of the millennium of the name of Lithuania in 2009.
