Forest Abbey is a Benedictine Abbey founded in 1105, beside a creek, a tributary of the Zenne, southwest of the city of Brussels. The abbots of Affligem, which had been the ecclesiastical owners of the parish since the bishop of Cambrai ceded it to them in 1105, decided to build a priory for women in Forest, Forest Abbey. The first abbess of the Forest priory was named in 1239. Also in the 13th century, the Romanesque church of Saint Denis was rebuilt in the newer Gothic style. The neighbouring abbatial church was rebuilt in the 15th century.
Relics of Saint Alena, whose cult was popular in the region, were formerly kept both in the parish church and in the abbey church, but since 1796 only in the parish church.
Much of the abbey was destroyed by fire on 26 March 1764. The abbey was suppressed on 8 October 1796 and sold the following year. The buildings that survived the dismantling are now a cultural center for seminars, banquets and exhibitions, owned by the Brussels municipality of Forest.

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.
