About

With traditional shop fronts, colourful hanging flower baskets and a gorgeous view of Dublin Bay, picturesque Portmarnock is a homely village that retains its historic character. Visit the medieval castle, stroll to the marina and down to the beach, before discovering the town’s charming cafés and chic boutiques.

The district’s name derives from the Irish word port – meaning port – and Saint Marnoch or Mernoc, said[6] to have arrived in what is now Portmarnock in the 5th century AD.The area had been settled in Neolithic times, with a number of remains of activity in the area still evident today, such as flints and other tools having been excavated at the northern fringe of Portmarnock. Further, the remains of a ring fort are visible from the air at the south of the town. The son of Queen Maedhbh of Connaught – Maine – is also said to have been buried locally.
