St. Mamertus Excavations
The excavations of St. Mamertus in Triesen represent one of Liechtenstein's most significant archaeological monuments. The site includes the remains of a Roman villa and the foundations of an early Christian chapel dating from the 5th or 6th century. These sacred buildings bear witness to the early Christianization of the Alpine Rhine Valley and the continuity of settlement since antiquity. Systematic excavations in the 1960s provided valuable insights into the architectural development of the site over several centuries. Today, the preserved ruins are open to the public and offer a glimpse into the Roman and early medieval history of the region. Its location on the slope also provides a strategic overview of the Rhine Valley, highlighting the historical importance of the site. It is a protected cultural asset of national importance.
