Architectural blueprints displaying secure door installations and heavy iron window grates for a confinement facility in Rome 插畫檔

This technical engineering engraving presents detailed architectural specifications for the heavily reinforced doors and barred window assemblies designed for a standardized correctional cell. Produced during the nineteenth century, these geometric layouts and cross-sections illustrate the security hardware and structural barrier methods utilized in Italy to enforce confinement. The diagrams precisely map out bolt patterns, locking mechanisms, timber door thickness, and multi-pane window ironworks alongside dimensional measurements scaled at one to twenty-five.
