One of Spain's biggest tourist locations, Barcelona, was graced with magnificent views on Monday morning. The 'back bone of Mallorca' the UNESCO World Heritage sight Serra Tramuntana. This image was taken by the Observatory Fabra Alfons Puertas and such a view can only be seen in certain weather conditions. With good visibility, no clouds and low light in Barcelona were exactly what made this view possible. The stretch of Mediterranean sea that separates Barcelona and Mallorca is 206 kilometres.
