Great Britain is not a country, a state or a nation - it is an island - one of the two large islands which, together with around 1000 small offshore islands, make up the British Isles. As such, Great Britain does not have a capital.
The island of Great Britain plus the northeastern part of the other large island (Ireland) and most of the small islands make up the United Kingdom of Great Britain and Northern Ireland.
