The UK - London

First of all , I´d like to say something about (generaly) capitals. There are young capitals , which were built especially for serving as capital( Washington) , another young cities get title because of some political or cultural changes. Some cities sometimes become capitals not due to their importance , „but because people aren´t able to choose another one(F.e. in Australia - Sydney as well as Melbourne have been so imporatnt and large , that Canberra has become the capital).But there are also cities which have always been the largest and „ the most important ones“ , the heart of that country. Those can be f.e. Prague or London.
