List of castra by province

Castra (Latin, singular castrum) were military forts of various sizes used by the Roman army throughout the Empire in Europe, Asia and Africa.

[1] The disposition of the castra reflects the most important zones of the empire from a military point of view.

Other castra were located in strategically important zones, as in Egypt, from which most of the wealth of the empire came.

Finally, other castra were located in zones in which the Romans experienced local unrest, such as Northern Spain and Judea.

Provinces where the Roman power was unchallenged, such as Italy, Gaul, Africa and Greece, were provided with few or no castra.
