Note: Logroño was one of the pilgrimage sites on route to the Cathedral of Santiago de Compostela, home of the shrine dedicated to Saint James, the patron saint of Spain. The symbol of Saint James, the scalloped shell, became the primary symbol representing pilgrims. Various pilgrimage routes in the autonomous communities of Aragon, Navarre, and León correspond to old Roman roads built in the northern portion of the Iberian Peninsula. Its wool production and location on the medieval pilgrimage route to Santiago de Compostela led to its growth. Churches in Logroño include the 11th-century Santa María del Palacio, 16th-century Santiago el Real and 15th-17th-century Santa María la Redonda.
