Niedermunster Abbey, situated at the foot of Mount Saint Odile was founded around 700 AAD by Saint Odile of Alsace, who was also the first Abbess.
Until the end of the 12th century, the two abbeys formed a single institution, but from the beginning of the 13th century, they began to operate as separate establishments. In 1542 the abbey came under the authority of the Great Chapter of Strasbourg Cathedral.
The Abbey buildings of which the ruins are still visible today were built between 1150 and 1180 AD. The Abbey was seriously damaged during the Peasants' War in 1525 and again by two fires, in 1542 and 1572. The nuns abandoned the abbey in 1545 and it was never reoccupied.
The site was then used, up until the 19th century, as a quarry for other buildings, including the adjacent farm.
For several centuries the abbey was known for its relics, the head and arm of Saint Lazarus of Marseille. When the abbey was burnt down these were transferred to Andlau, eventually disappearing during the French Revolution.
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.
