St. Magnus Cathedral was founded as a final resting place for the relics of St. Magnus. Work on its construction started in 1137. The Cathedral's founder was Earl Rognvald who supervised the earliest stages of the building during the bishopric of William the Old of Orkney (1102-1168).
Between 1154 and 1472, Orkney was ecclesiastically under the Norwegian archbishop of Nidaros (Trondheim) and after that it became part of the Scottish province of St. Andrews. The Cathedral was assigned to the inhabitants of Kirkwall by King James III of Scotland in a charter dated 1486. One of the most notable bishops was Bishop Robert Reid who held the see of Orkney between 1541 and 1558.
The Reformation brought ruin to many cathedrals but St. Magnus Cathedral seems to have emerged relatively unscathed, although the organ, treasures and rich vestments were removed and the wall decorations were covered in whitewash.
In 1845 the Government presumed the ownership of the Cathedral, expelling the then congregation and carrying out major restoration work to the fabric of the building. In 1851 the Royal Burgh of Kirkwall re-established ownership of the building and the choir and presbytery were fitted with new pews and galleries for the reinstated congregation.
The Cathedral slowly deteriorated until the early 20th century when The Thoms Bequest made further major restoration possible. Between 1913 and 1930, the main alteration to the exterior of the Cathedral was the erection of a tall steeple which replaced the low pyramidal roof of the bell tower. Internally, the screen separating the choir from the nave was removed, along with the pews and galleries. Stained glass windows replaced the formerly plain windows, much of the floor was tiled and the warm red sandstone was revealed by the removal of plaster and whitewash.
Today St. Magnus Cathedral is a popular tourist destination. The great age of much of its structure means it has smaller windows than those found in more modern churches. The tall narrow nave gives the illusion of much greater size than is actually the case. Uniquely in Britain, the Cathedral has a dungeon or holding pen built between the south wall of the choir and the south transept chapel. It is known as Marwick's Hole, but the source of this name and the time of its origin are unknown.
References:Tyniec Benedictine abbey was founded by King Casimir the Restorer probably around 1044. Casimir decided to rebuild the newly established Kingdom of Poland, after a Pagan rebellion and a disastrous Czech raid of Duke Bretislaus I (1039). The Benedictines, invited to Tyniec by the King, were tasked with restoring order as well as cementing the position of the State and the Church. First Tyniec Abbot was Aaron, who became the Bishop of Kraków. Since there is no conclusive evidence to support the foundation date as 1040, some historians claim that the abbey was founded by Casimir the Restorer’ son, King Boleslaw II the Generous.
In the second half of the 11th century, a complex of Romanesque buildings was completed, consisting of a basilica and the abbey. In the 14th century, it was destroyed in Tatar and Czech raids, and in the 15th century it was rebuilt in Gothic style. Further remodelings took place in the 17th and 18th centuries, first in Baroque, then in Rococo style. The abbey was partly destroyed in the Swedish invasion of Poland, and soon afterwards was rebuilt, with a new library. Further destruction took place during the Bar Confederation, when Polish rebels turned the abbey into their fortress.
In 1816, Austrian authorities liquidated the abbey, and in 1821-1826, it was the seat of the Bishop of Tyniec, Grzegorz Tomasz Ziegler. The monks, however, did not return to the abbey until 1939, and in 1947, remodelling of the neglected complex was initiated. In 1968, the Church of St. Peter and Paul was once again named the seat of the abbot. The church itself consists of a Gothic presbytery and a Baroque main nave. Several altars were created by an 18th-century Italian sculptor Francesco Placidi. The church also has a late Baroque pulpit by Franciszek Jozef Mangoldt.
