According to this source, the Dingle Peninsula has three stone alignments, and possibly once had another two which have been destroyed.
Cuppage describes the "Gates of Glory" thusly: "This pair of standing stones is the northernmost element in a complex of megalithic monuments which are grouped at the SE end of the townland of Milltown (formerly Kilbrack), less than 2km W of where the Milltown river flows into Dingle Harbour." (Cuppage, Judith. Archaeological Survey of the Dingle Peninsula: a Description of the Field Antiquities of the Barony of Corca Dhuibhne from the Mesolithic Period to the 17. Century A.D. Ballyferriter: Oidhreacht Chorca Dhuibhne, 1986. 43.)
A 1907 account of the stones records that "these stones were being carried by Fion MacCool's labourers for a building in Ventry, but upon hearing the War-Cry for the battle of Ventry Harbour, they stuck them down like nine-pins and hastened to the fray."
