Castellum
Small tower or aqueduct tank in ancient Rome / From Wikipedia, the free encyclopedia
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.
