Architectural cross-section illustrates internal structural elements and furnishing configurations of a secure cell within the Perugia Prison 插畫檔

This technical architectural engraving demonstrates a vertical cross-sectional diagram detailing the precise structural dimensions and interior spatial division of an individual detention cell situated in Italy. Dating from the nineteenth century, the plate meticulously maps out the connection between the primary cell interior, an adjacent corridor space, and an external security gallery walkway. A structured French-language index at the bottom identifies key structural and logistical elements including a wall-attached cot, the entryway door, the central corridor, the outer gallery framework, and a secure window opening, all accurately rendered at an administrative engineering scale of 1:50 to record standardized penological design standards.
