Montebourg Abbey was probably established by William the Conqueror after the invasion to England (1066). The exact date is unknown, but it was before William's death in 1087. The abbey got lot of donations from the Dukes of Normandy and Kings of England until the 1180s. It had a large land property even in the southern England and the abbey grew up quickly in the 12th century.
The abbey suffered damages in the Hundred Years' War, but it was renovated in the mid-15th century. In 1562 Huguenots looted the abbey during the Frencg Wars of Religion. The first school in Montebourg was established in 1585 and in the 18th century it was used as Catholic poor house and rest home. But soon after the Great Revolution caused the decline of Montebourg Abbey. It was reduced to the state and monastic buildings were partially demolished. In 1842, the Vicar General of Coutances acquired what was by then only an enclosure of ruins, and set it up for the Brothers of Mercy, which he had just formed in order to promote Catholic education in the countryside. From there, the brothers have continued their work.References:
Stavanger Cathedral is Norway's oldest cathedral. Bishop Reinald, who may have come from Winchester, is said to have started construction of the Cathedral around 1100. It was finished around 1150, and the city of Stavanger counts 1125 as its year of foundation. The Cathedral was consecrated to Swithin as its patron saint. Saint Swithun was an early Bishop of Winchester and subsequently patron saint of Winchester Cathedral. Stavanger was ravaged by fire in 1272, and the Cathedral suffered heavy damage. It was rebuilt under bishop Arne, and the Romanesque Cathedral was enlarged in the Gothic style.
In 1682, king Christian V decided to move Stavanger's episcopal seat to Kristiansand. However, on Stavanger's 800th anniversary in 1925, king Haakon VII instated Jacob Christian Petersen as Stavanger's first bishop in nearly 250 years.During a renovation in the 1860s, the Cathedral's exterior and interior was considerably altered. The stone walls were plastered, and the Cathedral lost much of its medieval looks. A major restoration led by Gerhard Fischer in 1939-1964 partly reversed those changes. The latest major restoration of the Cathedral was conducted in 1999. Andrew Lawrenceson Smith is famous for his works here.
