The Thermes de Cluny are the ruins of Gallo-Roman thermal baths lying in the heart of Paris" 5th arrondissement. The present bath ruins constitute about one-third of a massive bath complex that is believed to have been constructed around the beginning of the 3rd century. The best preserved room is the frigidarium, with intact architectural elements such as Gallo-Roman vaults, ribs and consoles, and fragments of original decorative wall painting and mosaics.
It is believed that the bath complex was built by the influential guild of boatmen of 3rd-century Roman Paris or Lutetia, as evidenced by the fact that the consoles on which the barrel ribs rest are carved in the shape of ships" prows. Like all Roman Baths, these baths were freely open to the public, and were meant to be, at least partially, a means of romanizing the ancient Gauls. As the baths lay across the Seine river on the left bank and were unprotected by defensive fortifications, they were easy prey to roving barbarian groups who apparently destroyed the bath complex sometime at the end of the 3rd century.
The bath complex is now partly an archeological site, and partly incorporated into the Musée national du Moyen Age, and as such is the occasional repository for historic stonework or masonry found from time to time in Paris. The spectacular frigidarium is entirely incorporated within the museum and houses the Pilier des Nautes. Although somewhat obscured by renovations and reuse over the past two thousand years, several other rooms from the bath complex are also incorporated into the museum, notably the gymnasium which now forms part of gallery 9 (Gallery of French Kings and sculptures from Notre Dame). The caldarium (hot water room) and the tepidarium (warm water room) are both still present as ruins outside the Musée itself and on the museum"s grounds.
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.
