What does "see" in "the Holy See" mean?

The seat of the Bishop of Rome is called "the Holy See". What does "see" mean? Does it mean “Holy Sea”, as the word “see” could be an archaic spelling of the word “sea”. It would make sense, because there is an unholy sea in the Bible also, called “Lake of fire”. It sure sounds like “Holy Sea”, because it makes most sense language-wise.
