The bulwark terrace features six bartizans or projected turrets, these have lookout windows and ribbed cupolas at the vertices of the bulwark's polygonal form. In the terrace's centre, a parapet surrounds the open space of the patio on the lower level.
From 1580 onwards, a number of structures were added to the terrace to help increase the garrison’s number. These were later demolished to return the tower to its original state. On the southern side of the parapet stands an image of Our Lady of Safe Homecoming, also known as the "Virgin of the Grapes".
