Architectural schematics display technical structural details for the secure doors and windows within the Vridsloeselille 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 Denmark. Dating from the nineteenth century, the plate features comprehensive elevations, lateral cross-sections, and top-down floor layouts illustrating a heavy wooden door equipped with complex external locking systems, a small food pass hatch, and a circular inspection peephole. The lower and right-hand sections provide detailed architectural layouts of the masonry recesses, highlighting a multi-paned window frame assembly designed for optimal light and security, all meticulously drafted at an official administrative scale of 1:25 to record standardized penal infrastructure of the period.
