In the Roman Empire, the Latin word castrum (plural castra) was a building, or plot of land, used as a fortified military camp.
Castrum was the term used for different sizes of camps including a large legionary fortress, smaller auxiliary forts, temporary encampments and "marching" forts. The diminutive form castellum was used for fortlets, typically occupied by a detachment of a cohort or a century.
In English, the terms "Roman fortress", "Roman fort" and "Roman camp" are commonly used for castrum. However, scholastic convention tends toward the use of the word "camp", "marching camp" and "fortress" as a translation of castrum.
