Architectural schematics display technical structural details for the secure doors and windows within the Pallanza Penitentiary 插畫檔

This technical architectural engraving presents specialized engineering diagrams detailing the precise structural reinforcement and security mechanisms of entryways and windows configured for individual prison cells located in Italy. Dating from the nineteenth century, the plate features comprehensive elevations, lateral cross-sections, and top-down swing diagrams illustrating a heavy paneled wooden door reinforced with horizontal metal bars, large rivets, an advanced latch and lock mechanism, and a grated rectangular inspection hatch. The lower portion illustrates the window assembly, mapping out the hinged opening frames, the protective outer bars embedded into the masonry wall recesses, and the specific anchoring joints, all accurately drafted at an official administrative scale of 1:25 to document institutional standards of penal architecture from this era.
