Marques de Riscal

We are staying the night at the Frank Gehry designed Marques de Riscal hotel, in the village of Elciego in the Rioja region. I walked up a nearby hill, through vineyards, to take some photographs of the hotel in its valley/village setting. 

Later, we went on a tour of the winery which adjoins the hotel, where the delicious red Rioja is made.  During the tour an immense thunderstorm took place, just as we had arrived at the wine tasting room. So, what should we do?
