SAN MARTIN DE ALBELDA (R)
Possibly its origin would be an eremitic community from the Visigoth period. It is known that its foundation as a monastery took place around the year 925. From then on it acquired great importance thanks to donations from the kings of Navarre, being the residence of the bishops of Calahorra between 1033 and 1092. It consisted of buildings today disappeared and a number of counting still conserved, in which would be his scriptorium that produced important manuscripts and became a great cultural center with a library that deserved the attention of Alfonso X the Wise at the end of the 13th century.
