Nieuwenbosch Abbey was a Cistercian community established in 1215 in Lokeren. The original site was unsuitable because of the poor water supply and the nuns moved to the site in Heusden in 1257, when the name became 'Nieuwenbosch'. The abbey was stormed and largely ruined in 1579 by the Iconoclasts, and the nuns moved for greater security inside the city of Ghent and built new premises in what is now the Lange Violettenstraat, in part using stone taken from the ruined buildings at Heusden, where the land and the few remaining structures were in due course rented out to farmers. The community was dissolved in 1796 in the French Revolution.
The only visible remaining structure on the Heusden site is the former abbey farm, now known as the Bosseveerhoeve.
In 1948, on the site of the former abbey church (now the garden of the state horticultural college) was discovered a monumental effigy of Hugo II, castellan of Ghent (d. c. 1232), lord of Heusden and father of Hugo III, the most prominent benefactor at the time of the foundation of Nieuwenbosch. The effigy is now in the Ghent City Museum.
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.
