La obra coronada en la fortificación de Puerta Tierra (Cádiz) a través de la cartografía urbana del siglo XVIII

Most of the walls of Cádiz is mainly due to the works carried out on the seventeenth century. During this period the defenses of the Puerta Tierra wall –the city’s only terrestrial communication point– were expanded with the incorporation of new defensive elements, such as the so-called “crownwork”. However, it was during the eighteenth century when this defensive element acquired its last configuration, which did not correspond to the last planned project.
