Saint Peter of Nora (Iglesia de San Pedro de Nora) is recorded for the first time in a donation document of Alfonso III of Asturias in 905.
Given its similarities with the church of San Julián de los Prados and the church of Santa María de Bendones, it was probably built in the times of Alfonso II of Asturias. Declared National Monument in 1931, the church burnt in 1936 during the Spanish Civil War losing the roof. It was restored by Luis Menéndez Pidal y Alvarez.
This church has the construction style established in church of San Julián de los Prados: facing eastwards, vestibule separate from the main structure, basilica-type ground plan, central nave higher than the side aisles, with intersecting wooden roof and lit by Windows with stone lattice. The straight sanctuary is divided into three apses with barrel vaults. As a differentiating element, the apses were joined to each other through the dividing walls by semicircular-arched doors. Like all the churches from this period, there was a room over the apse, only accessible from outside through a trefoil window. The bell tower, separate from the church like in Santa María de Bendones, does not belong to the original construction, and stems from an initiative in the seventies by the architect and great restorer of Asturian Pre-Romanesque, Luis Menéndez Pidal y Alvarez.
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.
