Moat

castles · defense · medieval

Protection ring. A moat is a deep, broad ditch surrounding a castle or fort. It acts as the first line of defense, making it much harder for enemies to attack the castle walls.

Water or dry. Some moats were filled with water to stop attackers and their horses, while others were left empty. Both types worked well because the steep sides were dangerous to cross.

Grew into lakes. Over time, some moats evolved into bigger water defenses like artificial lakes, dams, and sluices that protected entire towns and regions.

Pretty and practical. In later periods, moats became less about fighting enemies and more about looking impressive. They also served as sewers to keep castles clean.

Ancient origins. Even older hillforts had ditches that worked like moats, showing that people have protected settlements with deep trenches for thousands of years.
