Murbach Abbey was a famous Benedictine monastery in a valley at the foot of the Grand Ballon in the Vosges. The monastery was founded in 727 by Eberhard, Count of Alsace, and established as a Benedictine house by Saint Pirmin. Its territory once comprised three towns and thirty villages. The buildings, including the abbey church, one of the earliest vaulted Romanesque structures, were laid waste in 1789 during the Revolution by the peasantry and the abbey was dissolved shortly afterwards.
Of the 12th-century Romanesque abbey church, dedicated to Saint Leodegar (St. Léger), only the transept remains with its two steeples, and the east end with the quire. The site of the nave now serves as a burial ground. The building is located on the Route Romane d'Alsace.
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.
