The Carpathian Troy Open-Air Archaeological Museum is located in Trzcinica, in the south-east of Poland, in the Subcarpathian Voivodeship, a few kilometres to the north-west of Jasło, in the Ropa Valley.
The location of the Museum is among the oldest archaeological sites in Poland, and is of particular importance to the knowledge about the prehistory of the entire Central and Eastern Europe.

During the research and excavation works, especially those conducted since 1991 by Jan Gancarski, over 160 000 artifacts have been found, such as vessels, pottery, earthenware, objects made of flint, bones, antler as well as of iron and bronze. Many of these unique relics are considered to be wonderful pieces of prehistoric art and craft.
Trzcinica is the site where one of the first strongly fortified settlements found in Poland was discovered. The settlement was built in the early Bronze Age, over 4000 years ago. It was also here that the first settlement of Carpathian Basin Otomani-Fűzesabony culture in Poland was discovered, dated 1650-1350 BC and showing significant Mediterranean influence. Due to the significance of this discovery, the chronology and the distinct South European influence, the place was called Carpathian Troy.
