During the 10th and 11th centuries, a period during which Galician nobility become related to the royal family, Galicia was at times headed by its own native kings, while Vikings (locally known as Leodemanes or Lordomanes) occasionally raided the coasts. The Towers of Catoira (Pontevedra) were built as a system of fortifications to prevent and stop the Viking raids on Santiago de Compostela.
