What it is
The treaty promised religious tolerance to Irish Catholics and safe passage to France for Patrick Sarsfield's army — the “Wild Geese”. The English parliament then refused to honour it, which is why Limerick is called the City of the Broken Treaty. The stone was raised on its pedestal in 1865 and is the classic viewpoint for photographing King John's Castle across the river.
A plaque gives the story; the monument itself takes only a few minutes.
Getting there by bus
The stone stands at the western end of Thomond Bridge on Clancy's Strand, 15 minutes' walk from the city centre. Buses over Thomond Bridge stop beside it (Thomond Bridge stop).
Walk back across the bridge to the castle, or along the riverside to the Curragower falls and Sarsfield Bridge.
