The Cathedral Church of Saint German was built in 1879–84. The Patron of the Cathedral, St German of Man, was a Celtic missionary and holy man who lived from about 410 to 474.
The original cathedral of St German was inside the walls of Peel Castle and was built sometime in the 12th century when St Patrick's Isle was in the possession of Norse kings. At that time the church followed the Sarum Rite, prevalent throughout much of the British Isles. Around 1333 the Lords of Man refortified St Patrick’s Island and occupied the church as a fortress. In 1392 William Le Scroop repaired the Cathedral.
The building fell into ruin in the 18th century. After a considerable period of debate over who owned the ruins and site, it was decided not to rebuild that cathedral. The present building was constructed in 1879–84 to replace St Peter's Church in Peel's market place. In 1895, the bishop consecrated his chapel at the bishop's palace as pro-cathedral and instituted a chapter of canons with himself as Dean. That arrangement (bishop as dean) persisted even after the consecration of the new cathedral.References:
Castle Rushen is located in the Isle of Man"s historic capital, Castletown. The castle is amongst the best examples of medieval castles in the British Isles, and is still in use as a court house, museum and educational centre.
The exact date of castle is unknown, although construction is thought to have taken place during the reigns of the late 12th century and early 13th century rulers of the Isle of Man – the Kings of Mann and the Isles. The original Castle Rushen consisted of a central square stone tower, or keep. The site was also fortified to guard the entrance to the Silver Burn. From its early beginnings, the castle was continually developed by successive rulers of Mann between the 13th and 16th century. The limestone walls dominated much of the surrounding landscape, serving as a point of dominance for the various rulers of the Isle of Man. By 1313, the original keep had been reinforced with towers to the west and south. In the 14th century, an east tower, gatehouses, and curtain wall were added.
After several more changes of hands the English and their supporters eventually prevailed. The English king Edward I Longshanks claimed that the island had belonged to the Kings of England for generations and he was merely reasserting their rightful claim to the Isle of Man.
The 18th century saw the castle in steady decay. By the end of the century it was converted into a prison. Even though the castle was in continuous use as a prison, the decline continued until the turn of the 20th century, when it was restored under the oversight of the Lieutenant Governor, George Somerset, 3rd Baron Raglan. Following the restoration work, and the completion of the purpose-built Victoria Road Prison in 1891, the castle was transferred from the British Crown to the Isle of Man Government in 1929.
Today it is run as a museum by Manx National Heritage, depicting the history of the Kings and Lords of Mann. Most rooms are open to the public during the opening season (March to October), and all open rooms have signs telling their stories. The exhibitions include a working medieval kitchen where authentic period food is prepared on special occasions and re-enactments of various aspects of medieval life are held on a regular basis, with particular emphasis on educating the local children about their history. Archaeological finds made during excavations in the 1980s are displayed and used as learning tools for visitors.
