Description

This fortification plan, likely originating from the 18th century, illustrates a meticulously designed star-shaped fortification situated on a lake. The plan is annotated with measurements and labels, indicating strategic military design elements typical of European fortifications from the period.

The design features, including the geometric bastions and the concentric defenses surrounding the central donjon, are indicative of military architectural principles developed during the late Renaissance and refined in the subsequent centuries. These principles were largely influenced by the works of Sébastien Le Prestre de Vauban, a prominent French military engineer under Louis XIV, whose designs revolutionized fortification strategies across Europe. Vauban’s designs were characterized by their star-shaped bastions, which maximized defensive capabilities while minimizing blind spots.

The plan includes:

  • Donjon: The central, round structure labeled "Donjon" (also known as a Keep) served as the core defensive and administrative center of the fortification.
  • Bastions: The star-shaped bastions labeled with letters such as "e," "f," and "g" provided enhanced defensive positions, allowing crossfire to cover the approaches to the fort.
