King Willem-Alexander and Queen Maxima of the Netherlands have begun their three-day State visit to Ireland.
The royal couple were welcomed by Irish President Michael D Higgins and his wife Sabina to Aras an Uachtarain for their first official engagement.
The King and Queen were greeted at the steps of the Aras before the national anthems of the Netherlands and Ireland were played while 21 gun salutes were fired at intervals during the anthems.
The King then inspected the Guard of Honour before joining the Queen, President Higgins and Sabina in the state reception room where they signed the distinguished visitor’s book.
The Dutch Royals were also greeted by children from Gaelscoil Chomcille and De Medelief school.
In keeping with tradition, the Queen and King planted an alder tree in the garden of the president’s home.

The tradition was continued after Ireland’s independence, and the first tree planted by a president of Ireland was planted in 1939 by then president Douglas Hyde.
The State visit is the first by a Dutch head of State since Queen Beatrix’s visit in 1990.
