|Bastion of San Dalmacio||
A bastion is an angular structure projecting outward from the curtain wall of an artillery fortification. The fully developed bastion consists of two faces and two flanks with fire from the flanks being able to protect the curtain wall and also the adjacent bastions. Bastion fortifications offered a greater degree of passive resistance and more scope for ranged defense in the age of gunpowder artillery compared with the medieval fortifications they replaced.
The San Dalmatius, Southwest, and San Felipe, to the northwest, are equal to each other, there is a water tank and has access to pit.
