Christina of Norway (; 1234 – 1262) was the daughter of Håkon IV and his wife, Margaret Skulesdatter. She was born in Bergen. As part of an alliance she was betrothed to Philip, brother of Alfonso X of Castile. They married in 1258, and she lived in Castile until her death four years later. Tradition states that Christina desired that a church dedicated to St Olaf should be built in Castile. 750 years later, "a modernized version of [a] simple pre-Roman church" was built and dedicated in Covarrubias, Spain. Medieval source The primary source on Christina is that of Icelander Sturla Þórðarson (Sturla was a nephew of Snorri Sturluson and had come to Norway in 1263). Sturla was commissioned by Kristina's brother, Magnus Lagabøte, (King Magnus VI of Norway) to write his father's saga (Saga of Håkon Håkonsson ) shortly after King Håkon died in the Orkney Islands on 16 December 1263. In relating the stories in the saga, Sturla would have been able to interview contemporaries of the King and those that had taken the journey to Spain with Christina. In the 19th century, Norwegian historian Peter Andreas Munch related the story of King Haakon's daughter, Christina, in his work, A History of the Norwegian People (Det norske folks historie), which was published in the 1850s. The saga narrates how King Håkon sent a delegation to Castile in 1255 where they presented gifts to the court of falcons, furs, and leather. The Norwegian envoys were well received by the Spanish court and the next year when they returned to Norway, they were accompanied by representatives of Alfonso X, King of Castile, León and Galicia – headed by the royal notary, Sira Ferrant. Ferrant asked King Håkon if his daughter Christina could be betrothed to one of King Alfonso's brothers. The saga relates that King Håkon considered the request with careful thought. He consulted with the archbishop, and several wise men in making a decision. Håkon consented to the request under the condition that Christina be allowed to choose her husband from among the brothers of the King of Castile. (King Håkon had lost a son only a short time before to illness). The journey to Spain Christina left Tønsberg, Norway in the Summer of 1257 – the procession consisting of more than 100 people. After crossing the North Sea to Yarmouth, England, they crossed the English Channel to Normandy
