The Riestra Foundation was born thanks to the assets contributed by the Riestra Figueroa’s family. The first of the Riestra's who arrived to this area was Joaquin Riestra, an Asturian pilot, belonging to a bourgeois family of sailors, who arrived to Fisterra after years of sailing and after getting married in the first years of the 19th century. His first wife was Josefa Lobelos, with whom he had two children and, when he was widowed, he married her sister, Benita Lobelos, with whom he had no descendants. Joaquin Riestra died in Fisterra on the 20th of February 1854.
His sons, Manuel and José, lived in Corcubión (Manuel was the mayor of Corcubión between 1846 and 1849, and also in 1855). José Riestra, the other son, was a pilot like his father. He married María Figueroa from Corcubión, with whom he had three children: Laureano, Joaquina and Ana Riestra Figueroa.
Laureano Riestra Figueroa worked as a pilot for a big English company where he made a large fortune in addition to what he inherited from his parents. Laureano lived in England and was single. When he became ill he decided to return to Corcubión to live with his sisters and brother-in-law, Emilio Alonso (married to Joaquina). Laureano, like his uncle Manuel, was also the mayor of Corcubión between 1887 and 1890, the year in which he died at the age of 53. He left his fortune to his sisters under the condition that a nursing home was built for the homeless elderly.
The years after Laureano's death passed but his last wish was not fulfilled. What they did was to buy a piece of land just next to the family home, where they built a good house, and Ana, Joaquina and her husband Emilio moved in. In 1904, Joaquina died and, as she had no children, her assets were passed on to her husband with the aim of uniting the inheritances of the two sisters after the death of her sister Ana to build the nursing home that Laureano would have ordered. It was in 1910 when Ana died, and the entire estate of the Riestra Figueroa’s family passed into the hands of Emilio Alonso.
Emilio Alonso, a medical examiner, married Pilar Hermida Orbea in a second marriage. When he died, the whole legacy of the Riestra Figueroa’s family that was in the hands of Emilio Alonso passed to Pilar Hermida, so the creation of the longed-for nursing home was delayed.
It was in 1925 when Pilar Hermida gave up part of the inheritance received from her husband Emilio, specifically the first family home of the Riestra Figueroa’s family, to build the nursing home for the elderly homeless there, committing herself to giving 3650 pesetas every year for twenty years while she lived and the nursing home existed. It was named after Emilio Alonso, although it did not come into operation until 1926.
It should be noted that not only was part of the Riestra Figueroa family's fortune invested in the development of this nursing home, but also the contributions of Santiago Domínguez and Camila Andrade, both neighbours of Corcubión, who left part of their fortune for the nursing home for the elderly maintenance.
