(CNN) Donald Trump's hopes to protect his coastal Irish golf resort from erosion with a protective wall have been dashed by planning authorities.

Trump International Golf Links Ireland Enterprises bought the 18-hole Doonbeg golf course resort, which stretches along 4.5 kilometers (2.8 miles) of Ireland's Atlantic-swept coastline , in 2014.
