|Pamplona was an important town on the ancient road the medieval pilgrims took on their pilgrimage to Santiago de Compostela. Modern pilgrims still walk the road. Here a group of pilgrims are walking to the summit of a hill, where a metal sculpture memorializes their journey (next two slides).
Regarding the windmills, I took this quote from http://www.worldwatch.org/node/1641
"Spain also emerged as a major player in the wind power industry in 1998. Spain added 395 megawatts of wind power, pushing the country's overall capacity up 86 percent to 850 megawatts. In the northern industrial state of Navarra, which has a particularly active wind energy industry, 23 percent of the state's electricity already comes from wind turbines, most of them manufactured in local assembly facilities that employ hundreds of workers in the area around Pamplona."
