Newcastle, Saint Kitts and Nevis  Newcastle is a village on the northern coast of the island of Nevis in Saint Kitts and Nevis. It is the capital of Saint James Windward Parish. The village is just to the east of the Nevis airport, and in fact much of the village had to be moved over when the runway of the airport was extended a number of years ago. One building that was demolished was an early (17th century) colonial fortification called the Newcastle Redoubt.
