Royal Port

In England, historically this designation allowed the port to receive certain goods and collect certain associated taxes.

These tolls or "customs" on imported or exported goods formed one of the oldest prerogatives enjoyed by Kings of England.

The Kings of England designated Royal Ports in Ireland, such as Dublin, as part of their conquest.

In a bid to gain favour with Edward III over New Ross, the Roll was drawn up in a pictorial and colourful style showing that the city had had relationships with kings going back centuries.

King John wanted to turn Liverpool into a Royal Port as it offered a natural sheltered harbour, close to royal estates from which supplies could be withdrawn for military purposes as part of his conquest of Ireland.
