The contribution intends to bring to the attention of the scientific community the important Heritage made of plastic models, more or less homogeneously spread throughout Europe, which constitutes a patrimony of knowledge that links theoretical contributions on fortification, realizations, historical studies, archive documentation, technical representations, surveys, iconographic material.
Cartagena de Indias, one of the main Spanish commercial ports in the Caribbean Sea, was strategically built on a system of islands and peninsulas that formed a lacustrine system along the coast of Tierra Firme, known today as Colombia. For several centuries, Cartagena fortifications have been at the fore-front of Spanish military technologies. This site became the scene of action of the main military engineers at the service of the Spanish crown. In 1586 Battista Antonelli received from King Philipe II the task to design this monumental defensive system.
