Sociedad Deportiva Ponferradina was founded in 1922. The first idea of the executive committee to arrange a stadium was to build it inside the castle of Ponferrada, which was eight centuries old. King Alfonso XIII denied the building permit, which led to the construction of Santa Marta; the opening match was played 8 September 1923, a friendly against Cultural y Deportiva Leonesa. Ponferradina spent the vast majority of its professional years in the fourth and third divisions. In 1967, with the club in the former category, it achieved an historic 6–1 win against La Liga giants Real Madrid. Eight years later, due to financial difficulties, Santa Marta was sold, and the team relocated to Fuentesnuevas.
