Between the 1980s and 1990s, the Almoina site in Valencia was excavated by the SIAM (Municipal Service of Archeological Research) and also, in the following decade, the subsoil of the Almudín and the San Luis Beltrán square. In these surveys, remains of the fortifications of the Alcazar were found, as well the royal cemetery and the palatine dwellings that were presumably inside the enclosure. However, the excavation has been partial and not allowed us to understand the functioning of the complex.
The objective of this research is regarding the construction techniques used in the military architecture of Cittadella-Fortezza (Ancona, Marche, Italy). In this case, attention will focus primarily on historical, bibliographic and archive research, then through a comprehensive analysis of building methods used in the sixteenth century and on the strategic function that this fortification covered in the coastal strip of the Middle Adriatic.
The citadel of Turin, built in the sixteenth century by the duke Emanuele Filiberto, became an expensive and obsolete object that hampered the enlargements during the nineteenth century. The Enlargement Plan for the capital designed by Carlo Promis (1851-1852) progressively reduced the military constraints facing the citadel. In 1856 the City Council decreed the demolition of the defensive structure. During the demolition one section of the building was spared: the donjon.
