Instituto Español Giner de los Ríos is a Spanish international school in the civil parish of Algés, Linda-a-Velha e Cruz Quebrada-Dafundo, in the municipality of Oeiras, in the Portuguese Greater Lisbon region, operated by the Spanish Ministry of Education.

[2] At the end of the 1935-36 course year, the management of the Instituto and the Escuelas de Enseñanza Primaria were unified in a building along Rua Mousinho da Silveira.

[2] At that time, it moved operations to its current location, at Rua Direita do Dafundo, in the estate Quinta de São João do Rio, a historic monument ordered constructed by the Count of Cantanhede in 1649.

Many notable people have lectured at the institute, including D. Manuel A. Ivot Leon, eminent professor of history and American studies; D.Eugenio Montes, renowned poet and professor of literature; and others, including Gerardo Diego, who lectured several courses.

[2] As can be expected, there was a special attention placed on Portuguese studies, supported by the library and well-known personalities, including the illustrious historian Fidelino Figueiredo.
