Aulne Abbey was a Cistercian monastery, founded by Saint Landelinus about 637. Before 974 the Benedictines were replaced by secular clerics leading a common life, who, however, embraced the Rule of St. Augustine in 1144.
At the instance of Henry de Leyen, Bishop of Liège, it came into the hands of Cistercian monks from Clairvaux in 1147, under Franco de Morvaux as its first Cistercian abbot. From that time onwards it flourished as a Cistercian monastery.
The French burned it at the end of the 18th century, only a short time after it had been rebuilt on a larger scale. The library, which contained 40,000 books and 5,000 manuscripts, was also destroyed.

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.
