Here's why it's significant:
* The Down: The word "down" refers to a grassy hill in the English countryside. These hills are common in the South of England where the story is set.
* Watership: This specific hill, "Watership Down," is located in Hampshire, England. It's a real place with a rich history.
* Symbolism: The choice of this name is symbolic. It represents a place of safety, freedom, and a new beginning for the rabbits who have escaped from a dangerous warren.
The author, Richard Adams, chose this specific location because it was a place he knew well and was deeply connected to. It also served as a physical and metaphorical landmark in the rabbits' journey.
