A precious 700-year-old manuscript will be on view at Bangor Cathedral for one day when a service is held to celebrate its return to the city.

The Bangor Pontifical is a 14th Century bishop's manuscript, containing blessings and text of plainchant.

It has recently been conserved and rebound, but will now be kept for safety in Bangor University's archive.

A service on Sunday will include several plainchant melodies newly transcribed from the document.

The manuscript, which contains music notation and Latin text for services conducted by a bishop throughout the year, can also be seen online.

It includes instructions and the text to be used for bishop to dedicate churches, altars and cemeteries, as well as blessings....
