The Normans introduced large numbers of castles and fortifications including Norman keeps, and at the same time monasteries, abbeys, churches and cathedrals, in a style characterised by the usual Romanesque rounded arches (particularly over windows and doorways) and especially massive proportions compared to other regional variations of the style.
These Romanesque styles originated in Normandy and became widespread in northwestern Europe, particularly in England, which contributed considerable development and where the largest number of examples survived.
Grand archways are designed to evoke feelings of awe and are very commonly seen as the entrance to large religious buildings such as cathedrals.
The arches are supported on massive columns, generally plain and cylindrical, sometimes with spiral decoration; occasionally, square-section piers are found.
[4] Viking invaders arrived at the mouth of the river Seine in Normandy in 911, at a time when Franks were fighting on horseback and Frankish lords were building castles.
Over the next century the population of the territory ceded to the Vikings (now called Normans) adopted these customs as well as Christianity and the langue d'oïl.

Revolts characterised the region until well into the twelfth century and minor lords sought to resist ducal or royal power from within their own castles.
Their clever use of the local stone artisans, together with the vast riches amassed from their enslaved population, made such tremendous feats possible, some as majestic as those of the ancient Roman structures they tried to emulate.
[10] Other examples of great importance are the portal of the Shrine of Mary Queen of Anglona and the ambulatory and radiating chapels of the Aversa Cathedral.
Many have been demolished and rebuilt over the years (especially after the 1693 Sicily earthquake which destroyed many old Norman buildings), however some fortresses and houses still exist in Mdina and Vittoriosa.
