Fusiliers' Arch, Memorial arch at St Stephen's Green entrance, Dublin, Ireland

The Fusiliers' Arch is a granite structure at the Grafton Street entrance to St Stephen's Green, rising approximately 10 meters into the air. Limestone plaques with inscriptions and bronze decorative elements mark the monument, making it a notable landmark in central Dublin.

The monument was erected in 1907 to commemorate soldiers who died during the Second Boer War in South Africa from 1899 to 1902. Its standing in Dublin became complicated by the bullet marks it sustained during the 1916 Easter Rising.

Because the Royal Dublin Fusiliers fought for the British crown in the Boer War, nationalists called the arch "Traitor's Gate", and many Dubliners still use the name. The Latin inscription on the western face reads Fortissimis suis militibus hoc monumentum Eblana dedicavit MCMVII, in which Eblana, a name on Ptolemy's 2nd-century map, stands for Dublin.

The arch stands at a clearly visible point at the park entrance and is easily reached on foot, especially when arriving from Grafton Street. Multiple bus lines run nearby, and the Luas tram Green Line has a station right at St Stephen's Green.

The names of 222 dead are inscribed on the underside of the arch, a detail easily missed by passers-by. The Latin dedication on the western face reads "Fortissimis suis militibus hoc monumentum Eblana dedicavit MCMVII" — Dublin dedicates this monument to its strongest soldiers, 1907.
