 This tower was probably constructed by the Order of Santiago (religious order) whose knight commander from 1440 to 1477 was Diego de Villegas.It is logical to think that the tower which is described in the Books of Visitors of the Order of Santiago is the same tower which is mentioned in "Las Relaciones de Felipe II", where the current tower of the Santa Catalina Church now stands.The descriptions of cardenal Lorenzana from the year 1788 tell us that the first settlers were Sorian shepherds who came seasonally with their herds, and, attracted by the fertility of the lands of La Moheda and La Veguilla, which neighbor the historic center, moved their homes here and became the founding population.
