The oldest remains of Bordeaux, the Palais Gallien designates the Roman amphitheater of Burdigala, the 2nd century, which still has beautiful arches, a monumental door and structural elements. A large part of the site occupied by the building is now covered with houses. During the the French Revolution, parts of the building will then be demolished to allow the sale of lots of land and the construction of homes. The remaining vestiges will be classified and confirmed only from 1840. The name of 'Palace Gallien' is the fruit of several legends and confusions around the origin and the dating of the ruins.

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.
