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 Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
