Association of Craftsmen in Copenhagen  The Association of Craftsmen in Copenhagen (Danish: Haandværkerforeningen i Kjøbenhavn) is an interest organisation based in Copenhagen, Denmark. Its 2,200 members are owners of small and medium large companies. It is affiliated with 35 guilds and industry organisations. The association was founded at the initiative of master joiner Lasenius Kramp in 1840 to promote the interest of craftsmen of all trades. Håndværkerforeningen acquired a former Freemasons' Hall on Kronprinsensgade (No. 7) in 1868. They had a 2000-volume library reading room and billiard room in the building but moved out after taking over Moltke's Mansion on Dronningens Tværgade in 1930. In 1880, the Craftsmen's Association acquired Moltke's Mansion on the corner of Bredgade and Fronningens Tværgade in Copenhagen. The following year the association expanded the building with a new wing with an assembly hall. Håndværkerforenignen owns a large number of residences in the Greater Copenhagen area.
