Iglesia de San Salvador is a Romanesque-style church located in the town of Fuentes, Villaviciosa. The church of San Salvador is documented in 1021 (via an inscription) as due to the patronate of Diego Perez, and consecrated by Bishop Adaganeo I. The church appears to have been built in the 12th-century. The diocese of Villaviciosa is mentioned in 1385 by the bishop of Oviedo, Gutierre de Toledo. The temple is mentioned in 1625 in documents of the Monastery of San Pelayo of Oviedo. In the 18th century it was a parish church. The church was declared an Artistic Historical Monument in 1931. During the Spanish civil war the church was burned, it was reconstructed in its prior form in 1950.
A processional crucifix, a bejeweled silver cross, with gilded wood, semiprecious stones and a Roman cameo from the church, one of the pinnacles of goldsmithery in medieval Asturian, were stolen in 1898 and sold to French and then American private collectors. In 1917 J. Pierpont Morgan donated it to the Metropolitan Museum in New York, where it now is exhibited.
References:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
