What was the moat used for?

Answer 1

When moats were in style, during times when your neighbors were far off and liable to want your land, some castles used a moat as a natural defence, when no other form of natural terrain advantage was at hand.

Moats were generally used as a deterrent, since sappers could dig under and drain them, or swimmers could cross and then set up ladders or other means to get across the wall, or even break down the gate to let the calvary in to wreak havoc.

So, in short; moats were used by digging a trench and allowing water; especially sewage water; to accumulate in it. Depending on the tastes of the Baron or other Lord who had the castle built, the moat could also be filled with sharpened stakes before being filled, for any people who tried to swim across or simply fell in. The common idea of moats being filled with alligators or other such beasties is mostly myth; it would be rather difficult to _MAKE_ voracious man-eating animals inhabit the moat, especially since they'd be a threat to the inhabitants.

Answer 2

Castle moats were a form of defense. They were culverts surrounding castle walls that were filled with water or wooden stakes, making it difficult for enemy troops or siege engines to approach the walls themselves.
The purpose of a moat was defensive and they were filled with water deep enough that they were too deep to wade through. The moat made anyone attempting to swim across highly vulnerable target. It also reduced the risk of tunnelling ( tunnelling was a serious form of attack to undermine part of a castle) and finally the vast amount of water would reduce the risk of fire. Sometimes moats would also have stakes placed in bottom so if a man fell into the moat he would be killed. There were no animals or dragons in the moat.
a moat is used for.........what the heck idk
A moat prevented people from using ladders to scale the walls of a castle or walled city. It also prevented siege towers from approaching. It also provided some protection against mining under the walls.

Moats usually had water in them. Sometimes they were empty, and even then they were useful.
so people could not come inside the castle.
