It has an area of 70,000 m2 (750,000 sq ft)[1] where twelve granite sculptures by international artists are displayed.

[5] The island is connected to both banks of the river by footbridges and pedestrian bridges, and its aquatic fauna includes ducks and carps.

At first, an intertidal plain was formed, but the Lérez found this obstacle on its way to the ria and sought another alternative route, thus opening a channel on the right side.

[7] Later, a project for the development of this space was carried out, with the creation of contemporary artworks by twelve internationally renowned artists,[8][9] which took as their central theme the granite of Galicia and the relationship of man with his environment.

[10] The island, which has been declared a protected natural area,[11] is almost a kilometre long[12] and has an elongated shape.
