What is the capital of antarctica?

Antarctica does not have an official capital as it is not a country and does not have a permanent population. It is a continent that is governed by an international treaty known as the Antarctic Treaty System, which prohibits any military activity and designates Antarctica as a scientific preserve.

The primary purpose of the Antarctic Treaty System is to ensure that Antarctica is used exclusively for peaceful and scientific purposes. The treaty was signed in 1959 by 12 countries and now has 54 signatory nations. Meetings and discussions related to the governance of Antarctica are typically held in various countries around the world rather than in a specific capital city within Antarctica.
