Saint Peter's day eve

Tonight is Saint Peter's night eve and in Barcelona people use to do some parties to celebrate it.
My family and I went with an excursions group (Els Blaus) to an hermitage in the mountain of Colserola.
It was a trip in the mountain just for one hour and a half to visit the ruins of the hermitage and celebrate drinking some cava wine and eating the typical bread in this days "La coca", and going back to the city.
All began at 20:00, in la Plaza de Sarrià, and we were back in town around 24:00.

In the background of the picture one can see the lights of the Llobregat river valey, next to Barcelona.
