Rock of Gibraltar from Linea de la Concepcion

The only time I haven't been able to enter an European country was a long time ago when I was not an European citizen yet and I didn't have a British visa to get into Gibraltar, the British Overseas Territory located on the southern end of the Iberian Peninsula next to the "Linea de la conception" town in Spain. In this picture you can see the famous Rock of Gibraltar and that was almost the end of my visit to this place. Today I would be able to cross this border without any problem.
