The memorial site is dedicated to the soldiers of Ireland, of all political and religious beliefs, who died, were wounded or missing in the Great War of 1914-1918. Irish men and women served with the Armies of Australia, Britain, Canada, New Zealand, South Africa and the United States.

The memorial site is also known as the “Irish Peace Park” or the “Irish Peace Tower”.

The tower was built as a symbol of reconciliation by An All-Ireland Journey of Reconciliation Trust and the support of the people of Messines (now called by its Flemish name Mesen). It was constructed using stones from a demolished workhouse in Mullinger, County Westmeath, Ireland. The design is that of a traditional Irish round tower dating back to the 8th century. It is 33.5 metres (110 feet) high. As part of the design the inside of the tower is lit up by the sun only on the 11th hour of the 11th day of the 11th month. This is the time at which the Armistice was declared and the guns fell silent on the Western Front after four years of fighting.

The Island of Ireland Peace Park was officially opened at 11:00 hours on 11th November 1998 by the then President of Ireland Mary McAleese in the presence of HM Queen Elizabeth II and King Albert II of Belgium. Each year a commemorative Remembrance Day service is held at the Tower at 11.00 hours on 11th November.
