Arles-sur-Tech is best known for its abbey, which allegedly holds the relics of Saints Abdon and Sennen in a sarcophagus called Sainte Tombe, traditionally believed to have been brought from Rome 10th century. Its waters are traditionally believed to hold miraculous healing properties.
The Benedictine abbey of Sainte-Marie was founded in 778 and is the oldest Carolingian abbey in Catalonia. The main square contains the houses which were the first to be built around the abbey.

Its most curious item though is a 4th century sarcophagus which once contained the relics of Saints Abdon and Sennen.
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.
