Accurate architectural floor plan mapping the structural dimensions, furniture arrangement, and integrated sanitation facilities of a prison cell in St. Petersburg 插畫檔

This technical architectural engraving provides a comprehensive top-down horizontal floor plan illustrating the internal dimensions, masonry thickness, and spatial organization of an individual confinement cell within a penitentiary facility. Created during the nineteenth century, these geometric schematics demonstrate the penal architecture and progressive public health models implemented within the correctional infrastructure of Russia. The detailed diagram uses an alphanumeric legend to map out the precise positioning of basic institutional furniture like a bunk bed, a table, and a stool, alongside advanced utility installations including a heating conduit, an integrated toilet compartment, and a localized water basin.
