Hornwork
Fortification element / From Wikipedia, the free encyclopedia
A hornwork is an element of the Italian bastion system of fortification. Its face is flanked with a pair of half-bastions. It is distinguished from a crownwork, because crownworks contain full bastions at their centers. They are both outworks.
