Bastion(redirected from bastioned)
Also found in: Dictionary, Thesaurus.
a pentagonal fortification erected at the corners of the fortress wall to fire at the area in front of or along the fortress wall or the moats in front of them. Bastions appeared for the first time in Italy at the end of the 15th century and in Russia in the 16th century, where they were called raskats until the 18th century. A fortress bastion in Russia and in other countries consisted of one or two earth ramparts for the placement of weapons: the first, or the main rampart, and the second, or cavalier, which was higher than the first. The front sides of the bastion were called faces; the sides, flanks; and the inner rear side was called the gorge. The parts of two neighboring bastions facing each other and the section of the barrier connecting them, called the curtain, formed the bastion front.
