Bratislava (, ), currently the capital of Slovakia and the country's largest city, has existed for about a thousand years. Because of the city's strategic geographical location, it was an important European hub due to its proximity to the advanced cultures of the Mediterranean and the Orient as well as its link to the rest of Europe, which were possible by the Danube River. Prehistory In the area where present-day Bratislava lies, three skeletons of the (Epi)Pliopithecus vindobonensis were found in the borough Devínska Nová Ves in 1957, dating to 25–15 million years ago. Teeth of the Griphopithecus suessi (formerly known as Sivapithecus darwiny or Dryopithecus darwiny), dating 14–10 million years ago, were also found in Devínska Nová Ves, this time in 1902. From the Paleolithic period, hand-axes and other stone tools of Homo heidelbergensis (from the periods about 0.45 million years and about 0.3 million years ago) and of Neanderthal man were found. The first known permanent settlements on the town's territory (Linear Ceramics Culture) was during the Neolithic period. However, during the Early Stone Age there was already a settlement in the general area. But this was not within the present territory of the city. The first known fortified settlement on the area of later medieval castle of Bratislava appeared in Eneolithic. In the Bronze Age there were settlements from both older and younger (Urnfield cultures) part of the period. On the area of later Devín castle one finds important clues to the final period of the Bronze Age (Podoli Culture), when a fortified settlement arose on the strategic place: rock-cliff over river Morava joining river Danube. Early Iron Age The early Iron Age brought a shift of the settlements focus again to the area of today's historical centre and the castle of Bratislava. This period is considered an epilogue to Central European pre-history and this is attributed to the migration of the Thracian tribes, which brought with them their version of the Hellenic civilization. Many archaeological finds support the theory that both the castle-hill and the area of the town (on an important river-crossing) formed an important seat of local Hallstatt Culture and that the richly furnished mounds (barrows) excavated on eastern suburbs of the city may have been burial grounds of princes. Late Iron Age The La Tène period is defined as from 450 BC to 50 BC. Celts (more exactly the tribe of Boii) formed
