Every year the evidence emerging from the site adds increasingly important data to what is known about the public-religious complex. The 2010 campaign was one of the most productive of the whole ten year investigation. The aim was to concentrate on furthering knowledge of one of the most important roads of Roman Iguvium. The basalt paved road discovered this year, made up of large stone blocks, was the continuation of a road uncovered during previous investigations. The road, about 4 m wide, flanked the north wall of the temple portico and probably headed towards the area of the Roman theatre. An investigation of the road’s foundations showed that it had been constructed following the most canonical instructions given by Roman treatises, thus with the use of four make ups: statumen, rudus, nucleus and summum dorsum. The most important discovery was the identification of the road’s terminal point. This completely unexpected discovery provided new and important data regarding the interpretation of the urban plan of Roman Gubbio. In fact, the Roman roads crossing ancient town were often interrupted on the edge of the public-civic area ( forum ). The edge of the basalt road was marked by a drainage channel into which a conduit flowed, probably linked to a substantial water supply system, yet to be completely excavated and which will be investigated in coming campaigns. The road stopped in the proximity of a closed structure, probably with a monumental entrance, of which the two lateral foundation plinths were still in situ. The excavations brought to light the make up, the so-called nucleus made up of lime, gravel and iron slag, on which was laid a rich flooring of limestone slabs. Traces remained of two of the structure’s walls, probably faced with plaster and polychrome marble slabs ( crustae ).

Such evidence suggests this was a very richly decorated building, situated at the end of the road and therefore at the beginning of the public area. The excavation also investigated sectors of the Guastuglia archaeological area. In fact, it was decided to undertake further investigations of a sector of the sanctuary excavated in 2007, corresponding to the eastern entrance to the portico surrounding the temple. The most precious finds and those with the greatest historic-artistic value came to light in this area, including a small marble sacrificial altar and a bronze surgical instrument, finely-decorated and extremely well-preserved. Numerous well-preserved bronze coins were also found, datable to the first centuries of the Roman Empire.

The 2010 campaign also saw the renewal of investigations in the Domus della Guastuglia, a structure characterized by rich mosaic decoration, already partially explored during the 1970s by the Archaeological Superintendency of Umbria. During the excavation phases the substantial remains of a corridor, paved in opus signinum with mosaic decoration and plaster faced walls, emerged.
