The Abbey of St. Jean des Vignes was a monastery of Augustinian Canons situated in the south western hills of Soissons. Only ruins remain, of which the west front is still one of the most spectacular pieces of architecture in the town.
The abbey was founded on St. John's hill in 1076 by Hughes Le Blanc. Initially built in Romanesque style, the first buildings were replaced at the end of the 12th century by those visible today. The west front was begun in the 12th century, although not finished until the 16th. The refectory and cellar date from the 13th century, parts of the cloisters from the end of the 13th century, while other parts are from the 16th century, as is the abbot's lodging.
When the abbey was suppressed during the French Revolution the premises were put to use for military purposes, and an arsenal was added.
The site was acquired by the town of Soissons in the 1970s and the remaining buildings are now occupied by educational and heritage-related bodies.
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.
