The Fusiliers' Arch is a monument which forms part of the Grafton Street entrance to St Stephen's Green park, in Dublin, Ireland.

[7] The arch was commissioned to commemorate the four battalions (two regular and two militia) of the Royal Dublin Fusiliers that served in the Second Boer war.

[9][4] The construction of the arch coincided with a time of political and social change in Ireland, and the colonial and imperial background to the dedication were anathema to a burgeoning nationalist movement – who labelled the structure "Traitor's Gate".

[10][11][12] Though damaged in a cross-fire between the Irish Citizen Army and British forces during the 1916 Easter Rising,[9][13] the arch remains "one of the few colonialist monuments in Dublin not blown up" in Ireland's post-independence history.

[10][12] Engraved on the western face is the Latin text, Fortissimis suis militibus hoc monumentum Eblana dedicavit MCMVII, "To its strongest soldiers, Dublin dedicates this monument, 1907."
