Santa Marta was initially built in the late 15th-century but rebuilt at the end of the 16th century by the Confraternity of Santa Marta, a confraternity of disciplinanti (or flagellants). To the right of the entrance, they built an oratory.
Of the original decoration only one altar remains, and traces of frescoes in the presbytery and some lunettes in the walls of the oratory. Deconsecrated after World War Two, it became the property of the Commune of Ivrea in the 1970s, who converted it into a conference hall. The Baroque portal was moved to the parish church of San Bernardino in Ivrea.

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.
