It is on the outside, because it is used to prevent people from entering the castle. If it was on the inside, there would be no use for it.
The water-filled trench around a castle is called a moat.
A moat is the small body of water that usually circles the outside of the castle.
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 cleaners. ;)
Originally Rochester castle had a drawbridge outside its main gate on the east side of the castle. Neither the gate nor the drawbridge exist today.
This is how you can drain the moat outside of the castle in Super Mario. You have to first go into the room that is located next to the hazy craze maze and jump into the water. Jump into the water and surface by the two columns. You have to then pound the two columns down. The moat will then drain.
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
Typically using a drawbridge: a bridge that was anchored on the castle side but not on the outside of the moat. The outer edge of the bridge would be lifted up to the top of the entranceway (using ropes or chains), to form a secure part of the castle wall.
A homonym for the trench around a castle could be "moat."
