La Rioja (Spain)
Spanish is the main language in La Rioja. In fact, Riojans like to point out that this is where the language was first written down, over a thousand years ago in the monastery of San Millán de la Cogolla. While La Rioja is a mostly rural province, the presence of the Camino de Santiago and the thousands of foreign pilgrims that pass through each year encourages some residents to learn the basics of English, French, German, or Italian. Nevertheless, a solid grasp of Spanish is recommended.
