Fortification Diagram: Moat and Bastion Structure Explained #256810 (License: Personal Use)

This black-and-white technical illustration depicts a classic bastion fort design, emphasizing two key defensive elements: a water-filled or dry moat (labeled 1) surrounding the structure, and an angular bastion wall (labeled 2) that eliminates blind spots and allows flanking fire. The cross-sectional view reveals layered masonry construction, earthworks, and strategic geometry used in early modern military engineering from the 16th to 18th centuries.
