Highly advanced Otomani-Füzesabony culture people arrived in Trzcinica area around 1650 BC, coming from the regions south of the Carpathian Mountains, and took over the settlement developed earlier by the Pleszów group, as they were settling the Wisłoka River drainage area. They assimilated the local population and created a more powerful stronghold by rebuilding and expanding with remarkable engineering ingenuity the existing structure. The Otomani people left over 60,000 identified relics (including, unlike those of the Mierzanowice people, numerous luxury bronze items), many of which are a manifestation of their close ties with the Mediterranean area cultures - whence the Troy connection. The Trzcinica fortress was burned, rebuilt and expanded again (to 2 hectares), and after 1350 BC abandoned for over two thousand years. The settlement was repopulated by the Slavs who around 770-780 CE built a massive gord here.
