The brick battlements appear after the fourteenth century, while the last sturdy door is dated 1536, of which one door is preserved, the Gothic entrance arch, under which you can still see the hinges; this gate, of which the key is preserved, like the other gates of Fossato, was guarded day and night (wax, armor, straw and wood were provided by the town tax payers, who also were required to provide bread, wine and such) still in the sixteenth century until (and shortly after) the submission to the Papal States in 1540. These years were severely scarred by aggressions, betrayal, plagues and hardships of all kinds. As on other occasions in the past, Fossato reacted with its legendary capacity for survival and defense.
