Near by, and in a vale leading to the south from the Ebro, the Moors built a fortress and called it Nájera. Conquered by the early kings of Navarra, it was raised to the dignity of one of the cathedral towns of the country; from 950 (first bishop, Theodomio) to 1030 ten bishops held their court here, that is, until the see was removed to Calahorra. Since then, and especially after the conquest of Rioja by Alfonso VI. of Castile, the city's significance died out completely, and to-day it is but a shadow of what it previously had been, or better still, it is an ignored village among ruins. Still further west, and likewise situated in a vale to the south of the Ebro, Santo Domingo de la Calzada ranks as the third city. Originally its parish was but a suffragan church of Calahorra, but in 1227 it was raised to an episcopal see. Quite recently, in the beginning of the nineteenth century, when church funds were no longer what they had been, only one bishop was appointed to both sees, with an alternative residence in either of the two, that is to say, one prelate resided in Calahorra, his successor in Santo Domingo, and so forth and so on. Since 1850, however, both villages--for they are cities in name only--have lost all right to a bishop, the see having been definitely removed to Logroño, or it will be removed there as soon as the present bishop dies. But he has a long life, the present bishop! The origin of Santo Domingo is purely religious. In the eleventh and twelfth centuries a pious individual lived in the neighbourhood whose life-work and ambition it was to facilitate the travelling pilgrims to Santiago in Galicia. He served as guide, kept a road open in winter and summer, and even built bridges across the streams, one of which is still existing to-day, and leads into the town which bears his name. He had even gone so far as to establish a rustic sort of an inn where the pilgrims could pass the night and eat (without paying?). He also constructed a church beside his inn. Upon dying, he was canonized Santo Domingo de la Calzada (Domingo was his name, and _calzada_ is old Spanish for highroad). The Alfonsos of Castile were grateful to the humble saint for having saved them the expense and trouble of looking after their roads, and ordained that a handsome church should be erected on the spot where previously the humble inn and chapel had stood. Houses grew up around it rapidly and the dignity of the new temple was raised in consequence. Of the four cities of Upper Rioja, the only one worthy of the name of city is Logroño, with its historical bridge across the Ebro, a bridge that was held, according to the tradition, by the hero, Ruy Diaz Gaona, and three valiant companions against a whole army of invading Navarrese.
