The Urueña castle was built around the year 1060 by the Castilian monarch Fernando I el Magno (the Great). It is built on the remains of a Roman fort. Overlooking the Tierra de Campos it has always been a strategically important place. Urueña was on the border between the two kingdoms Castilla and León. After many battles the kingdom of Castilla reconquered the castle in the year 1281.
The Queen Doña Urraca lived in this castle. Also Doña María de Padilla, mistress of King Pedro I of Castilla, lived here. Later the castle was used as a prison: Doña Beatriz Princess of Portugal was held here as one of the prisoners. From the 19th century it was used as a cemetery. Today only the exterior walls of the castle remain.
The stone church of Gamla Uppsala, built over the pagan temple, dates from the early 12th century. Due to fire and renovations, the present church is only a remnant of the original cathedral.
Before the arrival of Christianity in Sweden, Gamla Uppsala was the seat of Swedish kings and a ceremonial site known all over northern Europe. The settlement was home to royal palaces, a royal burial ground, and a great pagan temple. The Uppsala temple, which was described in detail by Adam of Bremen in the 1070s, housed wooden statues of the Norse gods Odin, Thor and Freyr. A golden chain hung across its gables and the inside was richly decorated with gold. The temple had priests, who sacrificed to the gods according to the needs of the people.
The first Christian cathedral was probably built in the 11th century, but finished in the 12th century. The stone building may have been preceded by a wooden church and probably by the large pagan temple.
