Comparative longitudinal elevations showing the interior furnishings, masonry framework, and dual-zone ventilation systems for a detention cell in Langholmen 插畫檔

This technical architectural engraving presents multiple detailed longitudinal cross-sections illustrating the interior layout, multi-tiered flooring, and climate control utilities designed for an individual confinement unit. Developed during the nineteenth century, these engineering profiles showcase the specific cell formatting and public health systems implemented within the penitentiary infrastructure of Sweden. The diagrams precisely map out the spatial arrangement of specialized institutional furniture against an alphabetical legend, detailing a unique combination bed-table assembly, a multi-shelf nightstand with an integrated washbasin, a wooden stool, and a chamber pot, while tracking integrated utility networks composed of localized heating pipes, fresh air intake channels, foul air extraction ports, and mechanical wall ventilators.
