The archaeological finds made on the Plunacker range from the Middle Stone Age through the Neolithic and Bronze Age to the Roman Age and cover a period of about 7,000 years. The site was discovered by accident in 1976 during drainage works, the archaeological investigation of the Bolzano Office of Historical Monuments exposed several buildings in the Eighties.

In 2009, the Archeoparc Villandro was opened. On an area of approx. 1,600 sqm it shows the remains of four buildings from the Roman and Middle Ages which were roofed to protect them from wind and weather. The permanent exhibition, on the other hand, has been arranged in the school building in the main village of Villandro, Santo Stefano (St. Stefan).

Several objects including Roman amphorae are on display. Nowadays, Villandro is among the most important archeological sites of the entire Alpine area, due to the sequence of layers of different periods of the Neolithic which are part of a vast settlement. And how to reach the Archeoparc? It is located at the Plunacker - literally Plun Field -, near the village centre and the tourist office. Another excavation site is 10 km away, also in the Valle Isarco: the Archeoparc Velturno.
