Puente la Reina, Navarre, Spain

The Romanesque arches over the Arga River at Puente la Reina, rising toward a peak in the middle and reflected in still water. The bridge dates from the 11th century, when a queen of Navarre had it built so pilgrims on the Camino de Santiago could cross safely; which queen is still debated. The bridge gave the town its name, and it is still the way walkers on the Camino leave town heading west. The hump-backed profile, with the tallest arches in the center, lifts the deck well above the river while keeping each span short enough for medieval masons to turn in stone. Arrive on foot from the old main street and you cross exactly as pilgrims have for nearly a thousand years.
