History of Dublin

The subsequent Scandinavian settlement centred on the River Poddle, a tributary of the Liffey in an area now known as Wood Quay. The Dubhlinn was a small lake used to moor ships; the Poddle connected the lake with the Liffey. This lake was covered during the early 18th century as the city grew. The Dubhlinn lay where the Castle Garden is now located, opposite the Chester Beatty Library in Dublin Castle. TáinBóCuailgne ("The Cattle Raid of Cooley") refers to Dublindrissa ratter ÁthCliath, meaning "Dublin, which is called AthCliath".

Middle Ages

Dublin was established as a Viking settlement in the 9th century and, despite a number of rebellions by the native Irish, it remained largely under Viking control until the Norman invasion of Ireland was launched from Wales in 1169. The King of Leinster, Diarmait Mac Murchada, enlisted the help of Strongbow, the Earl of Pembroke, to conquer Dublin
