El Mirador is built into a place where previously a battery of canons was installed for use in the war between Spain and the U.S.A. over Cuba in the nineteenth century. It was built in 1973, at a height of 479 metres above sea level. It is not simply an excavation in the cliff, but rather a building with two enormous buried domes, so as to hide the construction.
From this beautiful place, one can contemplate the beach at Risco, which can be reached by boat or on foot following the cliff path.
From the Mirador one can also see Las Salinas del Río; the oldest salt plains of the archipelago, which have been used since Roman times. Lastly, and to satisfy the most curious, the name of Rio, or river, comes from the thin stretch of sea of approximately two kilometres which separates La Graciosa and Lanzarote.
