The name Ogrobe is well documented and the following passage in Latin was written about the name of Ograbe: "et ecclesiam Sancti Uincentii in insula Ocobre dextris cum suis." (899, St. Vincent of O Grove). Its original form is Ogrobe, having suffered in more recent times as a result of a completely Spanish etymological process. As natural etymological evolution occurred, the segmentation of the initial vowel "O" was confused with the masculine singular article in Galician and is translated as "El" in Spanish.
It is a small peninsula joined to the mainland by an isthmus known as O Vao, leading to the A Lanzada beach to the west and the wide intertidal marsh complex Umia-O Grove to the east, which connects with the town of Sanxenxo. Likewise, in O Grove is the small island of A Toxa which is accessed by a bridge from the early twentieth century.
O Grove is a town of excellence tourism, with many hotels and campsites.
