Various additions have been made from time to time to the original Halle des Drapiers since it was finished in the year 1304, and of these the 'Nieuwerck' is the most interesting. The east end of the Halle was for a long time hidden by a number of wooden erections, which, having been put up for various purposes after the main building was finished, were known as the 'Nieuwe wercken,' or new works. They were pulled down in the beginning of the seventeenth century, and replaced by the stone edifice, in the style of the Spanish Renaissance, which now goes by the name of the Nieuwerck, with its ten shapely arches supported by slender pillars, above whose sculptured capitals rise tiers of narrow windows and the steeply-pitched roof with gables of curiously carved stone. Ypres had ceased to be a great commercial city long before the Nieuwerck was built; but the Cloth Hall was a busy place during the thirteenth and fourteenth centuries, when Ypres shared with Bruges the responsibility of managing the Flemish branch of the Hanseatic League. The extensive system of monopolies which the League maintained was, as a matter of course, the cause of much jealousy and bad feeling. In Flanders, Ghent, Bruges, and Ypres defended their own privileges against other towns, and quarrelled amongst themselves. The merchants of Ypres had a monopoly which forbade all weaving for three leagues round the town, under a penalty of fifty livres and confiscation of the looms and linen woven; but the weavers in the neighbouring communes infringed this monopoly, and sold imitations of Ypres linen cloth on all hands. There was constant trouble between the people of Ypres and their neighbours at Poperinghe. Sometimes the weavers of Ypres, to enforce their exclusive privileges, marched in arms against Poperinghe, and sometimes the men of Poperinghe retaliated by attacking their powerful rivals. Houses were burnt, looms were broken up, and lives were lost in these struggles, which were so frequent that for a long time something like a chronic state of war existed between the two places.
