Architectural cross-sections illustrate internal structural elements and furnishing configurations of a secure cell within the Freiburg Penitentiary 插畫檔

This technical architectural engraving demonstrates two vertical cross-sectional diagrams detailing the precise interior dimensions, spatial division, and furniture layout of an individual detention cell situated in the Grand Duchy of Baden. Dating from the nineteenth century, the plate features longitudinal views labeled section E-F and section G-H, mapping out the secure masonry environment, ceiling profiles, embedded plumbing lines, and mechanical window mechanics along the upper walls. A structured French-language index at the bottom identifies key structural and domestic elements including a wall-attached cot, a table, a stool, a storage shelf with hooks, a gas lamp, a call signal, heating pipes, a latrine toilet with its discharge and flush water conduits, an airflow ventilator, fresh air inlets, foul air extraction vents, and a security lock for securing the cot, all accurately rendered at an administrative engineering scale of 1:50 to record standardized penological design standards.
