castellation
English edit
Noun edit
castellation (countable and uncountable, plural castellations)
- (uncountable) The act or process of making a building into a castle.
- (uncountable) The addition of battlements to a building, as for example when a feudal manor house needed fortification against border-raider attacks.

Coordinate terms edit
