question: Where did Blanca Of Navarre, Queen Of Castile's husband die?
context: Title: Blanca of Navarre, Queen of Castile
  Passage: Blanca of Navarre ( aft. 1133, Laguardia, Álava – August 12, 1156) was Queen of Castile, the daughter of King García Ramírez of Navarre and his first wife Margaret of L'Aigle. Blanca married Sancho III of Castile, regent of Castile (subject to his father Alfonso VII) on February 4, 1151 in Carrión de los Condes, Palencia, after travelling from Calahorra, Logroño, in January. The marriage was arranged to insure closer ties between León-Castile and Navarre. As was traditional, Blanca confirmed documents with her husband, so her activity may be traced until 1155. On November 11, 1155 she gave birth to the future king Alfonso VIII. There appears to be no record of her activities after December 1155, and she died on August 12, 1156. The cause of her death seems to have been complications of a new pregnancy, a child named García. In addition, she had other children buried in the church of San Pedro in Soria, although they are not identified. That her death was caused by a pregnancy is recorded in an epitaph engraved on her tomb, however, the engraving did not survive a sixteenth-century reconstruction of the royal tombs in Nájera. Her sarcophagus lid was preserved, and it represents the queen's deathbed with members of the court, including her husband, mourning her passing. Blanca was buried in the pantheon of the Navarrese kings in the monastery called Santa María la Real of Nájera, to which Sancho made donations on her behalf. The sarcophagus of the queen is regarded as a primary example of the ability to express human emotions in visual images in the 12th century. Blanca and Sancho had two named sons:
  Title: Sancho III of Castile
  Passage: Sancho III (1134 – 31 August 1158), called the Desired ("el Deseado"), was King of Castile and Toledo for one year, from 1157 to 1158. He was the son of Alfonso VII of León and Castile and his wife Berengaria of Barcelona, and was succeeded by his son Alfonso VIII. His nickname was due to his position as the first child of his parents, born after eight years of childless marriage. During his reign, the castle of Calatrava-la-Vieja was conceded to Abbot Raymond Serrat of Fitero, who proposed using the lay brothers of his monastery as knights to defend this castle. These knights would give rise to the Order of Calatrava, which was confirmed in 1164 by Pope Alexander III. It was also in his reign that the Leonese and Castilian spheres of conquest against al-Andalus were decided in the Treaty of Sahagún (May 1158), besides an exclusion of the conquering rights and a possible division of the Portuguese kingdom among the two sons of Alfonso VII, which would come to nothing possibly due to the premature death of Sancho.
