What mark did the Normans leave in European culture?

The Normans made a great contribution to the development of the culture of Europe. They formed powerful states, for example the Duchy of Normandy, the state of England. During the raids on Ireland, the Normans erected Dublin Castle, Trim Castle. In the conquered lands, the faith of the Normans with the god Odin at the head begins to spread. Norman style emerges in architecture. In England, the creation of the epic “Beowulf” takes place. Of interest are also the myths of the Normans about giants, gods, heroes, warriors.
