Answer:
Wealth, grandeur and luxury.
Step-by-step explanation:
In the story "The Most Dangerous Game" by Richard Connell, General Zaroff's home in the island is described as a "chateau". This word is used more often to describe places that are of great stature, grandly made symbolizing the riches and wealth the owner must have. It also is symbolic of the luxurious living condition of the owner.
Though it may be big, it doesn't necessarily have to symbolize any form of secrecy to it's name. So also, the big house of General Zaroff also doesn't seem t have any form of secrecy to it. Rather, we see the protagonist Rainsford looking at the place from a far distance, with blinding lights all from one enormous building.
