Its history goes back to Viking times, starting as a business location called Dubh Linn (dark pool) which was mixed with a Celtic enclave.

Due to large areas of the ancient city was wood-made, only two cathedrals, part of the castle and several churches from XVII century (or before) have been conserved. The current structure of the city is therefore of the Georgian era, when the Anglo-Irish aristocracy began to build new houses in the city.

Dublin was the protagonist of a long struggle for its independence, which reached its climax when during Holy Week of 1916 a warfare swept through the streets. This date is commemorated in many monuments in Dublin.
