The Castle of San Faustino or Old Castle is located in the municipality of Grosio. It was strategically important for controlling the valley floor, the Mortirolo Pass, and the outlet of the Val Grosina. Naturally protected by the steep rocky slopes of the hill, it is surrounded at its base by the Roasco and Adda rivers. It is easily accessible on foot, beyond the Rupe Magna and the New Castle.
The castle first appears in a 1150 document belonging to the Curia Comense. The church dedicated to Saints Faustino and Giovita likely predates the castle itself, later being incorporated into it and transformed into a chapel. The dedication to these two Brescia martyrs may reflect economic and cultural ties between Valtellina and Valcamonica.
When the Venosta family abandoned the castle, likely around the late 16th century, the church also began a slow but inexorable decline.
Today, only a few ruins of the castle remain, dominated by the Romanesque bell tower of the Church of San Faustino and Giovita. Archaeological excavations have revealed new insights into the castle’s perimeter and historical role. The findings suggest that the northern structures seem to expand as if to embrace the entire hill. The preserved walls allow for the identification of the castle’s outline and related structures. The relatively narrow design, seemingly 'forced' to follow the hill’s morphology, suggests that it served less as a defensive structure and more as a prestigious display of power by the feudal lord who controlled Grosotto and Grosio.
It is likely that the castle was originally much larger than it appears today: a true fortified village modeled after an early medieval castrum, surrounded by a defensive wall that enclosed the entire hill. The oldest construction (6th century AD), identified during the 2000 archaeological excavations, corresponds to a primitive funerary shrine that contained two rock-cut tombs, interpreted as privileged burials.
The ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
