an isthmus (IS-mus)
An area of land bordered on three sides by water is a peninsula.
Spain, or more generally, the Iberian peninsula. Although technically, the body of water north of Spain is the Bay of Biscay, not the Atlantic Ocean.
Land bordered by water on three sides
A bay is a body of water bordered on 3 sides by land, and by definition the "4th side" is the ocean. Whether it is saltwater or freshwater will depend on where the water is from. If the bay is of an ocean, it will be of saltwater. If it is of a freshwater lake or river, it will be of freshwater.
