Built from a preexisting Moorish fort by the powerful local Feria house, Feria's impeccably revamped 15th-century castle enjoys spectacular panoramas in every direction from its hilltop perch; climb up onto the roof of the Torre del Homenaje for the full view. Inside, spread over three floors, is the excellent Museo Señorío de Feria, with detailed Spanish-language displays on the Feria family and its other nearby castles.
References: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.
