Definition: The word 'newcastle' means a town or place on the island of Ireland that sits at the tip of a peninsula called the Dingle Peninsula. It's located on the south coast of Ireland, near the Atlantic Ocean. The name 'Newcastle' was originally derived from Old Irish 'nacht' meaning "castle" and 'stara" meaning "fort." Over time, it became a nickname for an area that was often referred to as the "kingdom of the castle," or "the place where the castle stood." In modern times, Newcastle is one of Ireland's most popular tourist destinations and attracts many visitors annually.
