The moat cleaners. ;)
The water-filled trench around a castle is called a moat.
I think that the 'trench' you are thinking of is a moat. You could say that it is a trench full of water that surrounds the castle. If you are not thinking of a moat then I am sorry.
A moat is a body of water that circles a castle, and a drawbridge is part of the castle that lowers to allow people to cross the moat.
the moat around the castle was there to protect the castle when it came under attack. A moat is basically a circle river dug around the castle. Hope this helps
The moat is filled with sharks
A homonym for the trench around a castle could be "moat."
at the main way in if the castle has a moat or ditch.if there not moat of ditch then there no drawbrigde un less the castle ramdom
I would like a larger alligator for the castle's moat, please.
