Islas Medas located on the hill which is much higher than on photo. I bet this is Punta Arnella (east to Cap de Creus). In some old photos there is white building next to it

Now this building is absent which is confusing. Also see construction details - gray bricks and number of windows/doors, Islas Medas is slightly different.
