It is derived from the name Witteric; a Suebi king who ruled Gallaecia, Hispania and Septimania.

[2] (also known as: "Parroquias") Though the early settlers were of Celtic origin and the Romans knew about the therapeutic properties of the thermae, it was not till the arrival of the Suebi after the collapse of the Roman Empire that this Spa Town became really popular for the first time in the 6th century.

In the 14th century the entire Terra Chá Region (including Guitiriz and its capital Villalba) ended up as part of the domains of Fernán Pérez de Andrade whose family were to become the First Counts of Villalba during the reign of the Catholic Monarchs.

Amongst other remains in the area is a well conserved medieval fortification, the Castle of Parga, and a Gothic bridge.
