The provinces of Cantabria and Asturias are historic lands that lay claim to attractions ranging from fishing villages along the coastlines to the Picos de Europa, a magnificent stretch of snowcapped mountains. Cantabria was settled in prehistoric times and later colonized by the Romans. The Muslims were less successful in their invasion. Protected by the mountains, many Christians found refuge here during the long centuries of Moorish domination. Much religious architecture remains from this period, particularly Romanesque. Cantabria was once part of the Castilla y León district of Spain, but is now an autonomous region. Most tourism is confined to the northern coastal strip; much of the mountainous inland is poor and unpopulated. Away from the coast, you'll need a rental car because public transport is inadequate at best. Santander, a rail terminus, makes the best center for touring the region; it also has the most tourist facilities. From Santander, you can get nearly anywhere in the province within a 3-hour drive. The principality of Asturias lies between Cantabria in the east and Galicia in the west. It reaches its scenic (and topographical) summit in the Picos de Europa, where the first Spanish national park was inaugurated. With green valleys, fishing villages, and forests, Asturias is a land for all seasons. The coastline of Asturias constitutes one of the major sightseeing attractions in northern Spain. Called the Costa Verde, it begins in the east at San Vicente de la Barquera and stretches almost 145km (90 miles) to Gijón. Allow about 6 hours to drive it without stops. The western coast, beginning at Gijón, goes all the way to Ribadeo, a border town with Galicia -- a distance of 180km (112 miles). This rocky coastline, studded with fishing villages and containing narrow estuaries and small beaches, is one of the most spectacular stretches of scenery in Spain. It takes all day to explore. Asturias is an ancient land, as prehistoric cave paintings in the area demonstrate. Iron Age Celtic tribes resisted the Romans, as Asturians proudly point out to this day. They also resisted the Moors, who subjugated the rest of Spain. The Battle of Covadonga in 722 represented the Moors' first major setback in Iberia. Asturians are still staunchly independent. In 1934, Francisco Franco, then an ambitious young general, arrived with his Moroccan troops to suppress an uprising by miners who had declared an independent Socialist republic. His Nationalist forces returned again and again to destroy such Asturian cities as Gijón for their fierce resistance during the Spanish Civil War.
