rebuilt. Each of them had (and still has) a name as well as a house number: Auf'm Keller (1678), Hamels (1678), Melanders (1678), Op der Ley (about 1600 - refurbished 1911), Auf'm Haus (1678), Großer Klaus (1686 - rebuilt 1964), Kleiner Klaus (1678), Scholle (1678), Hinter'm Turm (1678), Jostenhaus (refurbished about 1738), Hechtsteinhaus (1678), Op de Trapp (1678) and Leonhards (rebuilt 1955). In 2001 a part of the historic Old Town yet again fell victim to the flames. During the night of 21 January 2001 a fire broke out which destroyed three of the old half-timbered houses. They had to be demolished, and have been replaced by modern buildings. Economics By the mid-19th century, more than 100 companies and businesses had established themselves, most of which were largish cottage industries, principally weaving on looms. After 1850, the first large-scale businesses, aided by steam technology, were created. Despite the strong industrialization of that time, the village's agricultural character was not completely lost, but today only isolated agricultural enterprises exist. Of particular significance was the arrival of quarrying in Wülfrath, with the establishment of the Rheinisch-Westfälische Kalkwerke Dornap in 1887, and the Rheinische Kalksteinwerke Wülfrath in 1903. Wülfrath now has the largest chalk and limestone quarries in Europe. These undertakings have been a decisive influence on the development of the town, and have remained the principal component of Wülfrath's industrial life until now. There continued to be numerous home-based weaving enterprises, as well as businesses involved in finishing leather and many other small firms. A branch of the Ford works at Cologne was founded here, rising out of the coachwork company Josef Hebmueller Soehne, established 1889, and still extant as (Tedrive). Coat of arms After 1840, the Wülfrath coat of arms, modelled on an old seal of the Lutheran Reformed municipality, was designed by the Düsseldorf heraldic and painter Wolfgang Pagenstecher. In 1938 the arms were again re-designed and officially recognized by the President of the Rhine Province. The arms, showing a shepherd in mediaeval costume fending off a wolf with his staff, symbolize the victory of good over evil and refer to the town's name, although not particularly to the settler Wolf.
