Honduras

Honduras is a Central American country. Its capitals are Tegucigalpa and its twin city, Comayagüela, though the Wikipedia article for Tegucigalpa applies for both cities. It's not common yet not rare either for countries to have two capitals. Bolivia is a good example. Côte d'Ivoire too. The Netherlands... well, The Hague is more the administrative centre. South Africa takes things to a whole other level, though, with three capitals.

Honduras is the home of Copán, an ancient Maya ceremonial site, and the Bay Islands a hotspot for divers known for its whale sharks.
