A team of archaeologists from the Office for the Preservation of Monuments and Archaeology have uncovered a large Roman complex during excavations in a gravel quarry near Cham-Oberwil, located in the canton of Zug, Switzerland.

The site is situated on an elevated position in the Äbnetwald region, where previous excavations have found evidence of settlements and graves from the Bronze Age and Iron Age periods.

Rescue excavations have been conducted in the quarry by the Office for Monument Preservation and Archaeology since the 1990’s, with a recent study finding a series of large Roman buildings and rooms which belong to a complex that extends over an area of at least 500 m2.
