Castellum
1. Limes watchtower, Germany (reconstruction)
2. Ruins of a castellum divisorium, France
A castellum[1] in Latin is usually:
- a small Roman fortlet or tower,[2] a diminutive of castrum ('military camp'), often used as a watchtower or signal station like on Hadrian's Wall. It is distinct from a burgus, which is a later Latin term that was used particularly in the Germanic provinces.
- a distribution, header and settling tank in a Roman aqueduct or castellum aquae.
It is the source of the English word "castle".
