Analytical architectural elevations illustrating the structural framing, utility connections, and plumbing infrastructure of a confinement cell in St. Petersburg 插畫檔

This technical architectural engraving provides precise vertical cross-sections detailing the internal elevations, masonry thickness, and utility systems designed for an individual detention unit. Developed during the nineteenth century, these detailed profiles showcase the progressive cellular isolation and institutional health models implemented within the prison infrastructure of Russia. The diagrams map out the spatial arrangement of localized cell fixtures, tracking the positioning of a secure entryway door with a food hatch, adjacent wall shelving, an adjustable gas lighting line, an integrated flushing latrine assembly, and a centralized fresh water fountain connected to dedicated multi-level hydraulic drainage and supply piping.
