an archaeological excavation in 2000 in the block behind number 47-51 have revealed several foundation works of old buildings and of the second city wall (15th-16th century) and one of its defensive towers, a corner of which was located in the alley packhusgränd passing north of the block. the troubadour carl michael bellman often used living individuals as prototypes for the numerous people appearing in his bacchanalian songs, and the model for "ulla winblad", a promiscuous woman, was "maria kristina kiellström" who took the name winblad ("wine leaf") from her stepmother. while it is not known how well acquainted she was with bellman, she did marry his friend erik nordström with whom she settled in norrköping in 1772. as her husband died in custody, she moved back to stockholm in 1782 and settled on number 47. in the meantime the songs of bellman had made her famous and everyone was charmed by her return to the capital. she was less flattered however, and it is said she gave bellman a blow at one occasion and her second husband is reported to have regularly complained he had married that 'lecherous woman'. her reaction is somewhat understandable, considering the often burlesque lyrics in the songs. below are 3 of the 21 verses of his 48th epistle named "varuti avmålas ulla winblads hemresa från hessingen i mälaren en sommarmorgon 1769" ("in which is depicted ulla winbladh's journey home from hessingen in lake mälaren a summer's morning 1769"), describing the trip back to stockholm from stora essingen in a rowing boat passing by marieberg where at the time was located a saltpetre work and a penitentiary.
