According to some sources, supported by finds in the foundations, the first religious building on the site of Brugnato Cathedral was constructed in the 7th century over a palaeochristian necropolis, the church of a monastery dependent on Bobbio Abbey, founded by and dedicated to Saint Columbanus. It was rebuilt in the 11th-12th centuries, passed to a resident community of Benedictine monks, and became in 1133 the seat of the diocese of Brugnato (suffragan of the Archdiocese of Genoa) which had spiritual authority over the middle and upper Val di Vara.
With the arrival of the Ghibellines during the 14th century, and the consequent flight of the bishop, who took refuge in Pontremoli, the cathedral lost importance, although it remained as the church of the abbey of the Benedictine community. In 1820 the diocese was merged into those of La Spezia and Sarzana-Luni to form a single diocese with its seat in La Spezia, leaving the abbey church with the title of 'co-cathedral'.
Restoration work in the 1950s brought about the rediscovery of the remains of the original Romanesque church which were the objects of study in 1994 when archaeological excavations conducted by the archaeological authorities of Liguria revealed the ancient perimeter walls, the floors and a baptismal font beneath the centre of the nave.
The groundplan is based on two asymmetrical naves separated by columns, a fairly common arrangement in the religious buildings of Lunigiana although less so in the churches of Liguria. Above the massive columns are thick semi-circular arcades.
There are differences between the two naves: the central and larger one is covered by barrel vaulting and ends in a semicircular apse with three single-light windows; the smaller side nave to the south however has bays of groin vaulting and terminates in a square wall inside within an external curved apse.
The interior, which is very sober, with few decorative elements retains traces and sculptured fragments from the ancient primitive church, as well as some frescoes among which, on the second column on the south, is one of the 14th century depicting Saint Columbanus giving a blessing; another, discovered during the works of 1994, is on the wall of the lesser nave and shows the Presentation in the Temple, in which may be recognised, not only Jesus, Joseph, Mary and the high priest, but also Saint Francis of Assisi and Saint Laurence.
A painting by Vincenzo Comaschi, dated 1821, depicts the Virgin Mary with the Infant Jesus on her lap among angels and Saints Francis and Laurence. Near the high altar is a polyptych showing Scenes from the life of Christ.
References: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.
