The Monastery of Royal Saint Mary of Iranzu is a Roman Catholic monastery located in Abárzuza, Navarre. It was founded by Pedro de Artajona in the late 12th century, being Artajona's place of burial upon his death in 1193. The Cistercian Order had a large part in its building throughout the 12th century.
It was dissolved in 1839 and confiscated by the State. It was abandoned and became ruinous until 1942, when the Provincial Government of Navarre refurbished it. One year after, a Theatine Fathers community was established there. The Cistercian-style church was built during 12th century. The cloister is partly Cistercian (12th century) and partly Gothic (13-14th centuries). Additional minor Renaissance parts were added during 17th century.
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.
