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 Kalozha church of Saints Boris and Gleb is the oldest extant structure in Hrodna. It is the only surviving monument of ancient Black Ruthenian architecture, distinguished from other Orthodox churches by prolific use of polychrome faceted stones of blue, green or red tint which could be arranged to form crosses or other figures on the wall.
The church is a cross-domed building supported by six circular pillars. The outside is articulated with projecting pilasters, which have rounded corners, as does the building itself. The ante-nave contains the choir loft, accessed by a narrow gradatory in the western wall. Two other stairs were discovered in the walls of the side apses; their purpose is not clear. The floor is lined with ceramic tiles forming decorative patterns. The interior was lined with innumerable built-in pitchers, which usually serve in Eastern Orthodox churches as resonators but in this case were scored to produce decorative effects. For this reason, the central nave has never been painted.
The church was built before 1183 and survived intact, depicted in the 1840s by Michał Kulesza, until 1853, when the south wall collapsed, due to its perilous location on the high bank of the Neman. During restoration works, some fragments of 12th-century frescoes were discovered in the apses. Remains of four other churches in the same style, decorated with pitchers and coloured stones instead of frescoes, were discovered in Hrodna and Vaŭkavysk. They all date back to the turn of the 13th century, as do remains of the first stone palace in the Old Hrodna Castle.
In 2004, the church was included in the Tentative List of UNESCO"s World Heritage Sites.
