The Magazine Fort is a bastion fort and magazine located within the Phoenix Park, in Dublin, Ireland. Built in 1735, it was occupied by British Armed Forces until 1922 when it was turned over to the Irish Defence Forces after the Anglo-Irish Treaty. The Irish Army continued to operate the site as an ammunition store through the mid-20th century. It was fully demilitarised by the 1980s. The fort is now managed by the Office of Public Works. As of 2015, it was in a derelict state and not open to the public, however some repairs were undertaken and the site partially opened for "limited guided tours" from 2016.

The Stone of Remembrance is a standardised design for war memorials that was designed in 1917 by the British architect Sir Edwin Lutyens for the Imperial War Graves Commission (IWGC). It was designed to commemorate the dead of World War I, to be used in IWGC war cemeteries containing 1,000 or more graves, or at memorial sites commemorating more than 1,000 war dead. Hundreds were erected following World War I, and it has since been used in cemeteries containing the Commonwealth dead of World War II as well. It is intended to commemorate those "of all faiths and none", and has been described as one of Lutyens' "most important and powerful works", with a "brooding, sentinel-like presence wherever used".
