Santa Maria Maggiore church is an example of First Romanesque art. It includes the oldest cross vaults in Italy.
The oldest document mentioning the basilica is a privilege by pope Paschal II, dated 22 August 1107. Archaeological studies showed that at least two churches existed in the site before the current one, the earliest one being perhaps contemporary to the annexed baptistery of San Giovanni ad Fontes (c. 5th-7th centuries). The basilica has a nave and two aisles with a lower transept. The façade was originally embedded in the city's walls, but later the first three bays were abandoned and a new façade was obtained by closing one of the internal arches with a new wall.
The nave is characterized by arches which, at the sides, have double mullioned windows at the sides. The pillars which do not support the arches are prolonged by blind columns up to the clerestory. The longitudinal arches (those separating the nave from the aisles) are supported by semicolumns which form the pillars. The aisles are a 14th-century reconstruction of the original ones. In 1944 a crypt, perhaps unfinished, was discovered.
Adejacent to the basilica is the nearly coeval Baptistery of San Giovanni ad Fontes.
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.
