Outside the Roman Vicus, in the area of today's road between Dillingen and Beckingen, the old B 51, a large Roman complex of a villa with five buildings on Hylborn was excavated based on the discoveries by Philipp Schmitt in the 1970s. The complex was begun in Celtic times in 90 BC and lasted to 234 AD. The largest building has a length of 68 m. The rooms partly enjoyed hypocaust heating and black and white mosaic floors, which are decorated with right- and left-turning swastikas. The luxurious building facilities also included a wooden water pipe, whose hollowed oak trunks were connected with iron sleeves and supplied the system with fresh spring water. By tree-ring dating the water pipe could be dated to the year 163 AD. The presence of Christians in Pachten is indicated by finds such as the "Ursus Stone", the tombstone of a three-year-old boy, discovered in the old church. The special meaning of the stone lies in the Chi Rho monogram XP, which was surrounded by two pigeons carved on the stone, in contrast to the other inscriptions. Such inscriptions are very rare in rural areas, since Christianity developed there later than in urban settlements. The peculiar orientation of the church to south-southwest-north-northeast, in the direction of the old Roman road, and the patronage of Maximin of Trier, who died in 346, indicate that already in late antiquity there was a Christian church in Pachten. When the later Romanesque church was torn down for construction of a Neo-gothic church in 1891 tombs from the Merovingian period were also discovered. These Frankish-Merovingian tombs were fenced with Roman stones. Based on further grave finds in the vicinity of today's church it appears that Pachten in the post-Roman period, lay in ruins only a short time, if at all, and was repopulated by at least the 7th century. Systematic investigations in the 20th century have to date uncovered more than 560 graves and the remains of temples, theaters, villas and houses. Most date to the third and fourth centuries AD. A wealth of glass, metal objects, remains of colored wall plaster, heaters, and pottery attest to prosperity. During construction work on the Dillinger Hütte site a grave was found in 2009 documenting the change from Celtic to Roman ways of life. Die in der Pachtener Kirche St. Maximin angebrachte Nachbildung des Grabsteins eines Kindes mit entsprechenden Symbolen belegt die damalige Rolle des Christentums.
