What is a Bastiment?

"Bastiment" is a word that is not commonly used in modern English. It is an archaic or obsolete term that was previously used to refer to a fortified building or structure, such as a castle or a fortress.

The word "bastiment" is derived from the Old French word "bastide," which referred to a fortified building or stronghold. Over time, the word "bastide" evolved into "bastiment," which was used in Middle English to refer to any type of fortified structure, including castles, fortresses, and other types of defensive works.

However, as military technology and architecture evolved over the centuries, the need for fortified structures decreased, and the use of the word "bastiment" fell out of favor. Today, it is rarely used in modern English, and is primarily found in historical or archaic contexts.
