The ruins of Whitby Abbey are among the most celebrated sights of North Yorkshire. The first monastery here, founded in about 657, became one of the most important religious centres in the Anglo-Saxon world. In 664 it was the setting for the Synod of Whitby, a landmark in the history of the Church in England. The headland is now dominated by the shell of the 13th-century church of the Benedictine abbey founded after the Norman Conquest.
