The fortress, built around 1500 by Giuliano da Sangallo on behalf of the Florentine Republic and completed in 1561 by Alberto Alberti at the behest of Cosimo I, is inserted in an edge of the city walls, develops on pre-existing structures and is made up of a quadrangular enclosure having puntoni a cuore at the corners that identify the Sangallo. The analyzed puntone shows San Gallo's invention: “il fronte bastionato per la difesa radente”. The discoveries made suggest that the fortress is the result of a renovation, enveloping new ones on existing structures.8Reconocimiento - No comercial - Compartir igual (by-nc-sa)Puntone de Santa Maria MaddalenaFortressSansepolcroMilitary architectureRenaissance fortificationsGiuliano da SangalloArchitectural restorationArquitectura militarFortificaciones renacentistasRestauración arquitectónicaComunicación en congreso10.4995/FORTMED2025.2025.20321Abierto
