The wood of the Knights Hospitaller
Kilmainhamwood was a preceptory of the Knights Hospitaller of St John, the military religious order the Normans brought to Ireland, founded originally to protect pilgrims on the road to Jerusalem. The order's Irish headquarters was at Kilmainham in Dublin, and this north-Meath holding - the wood of Kilmainham - took its name from that connection. The circular old graveyard in the village, roughly 63 by 57 metres, is the site of their church. A rectangular sandstone font and a carved cross slab survive among the stones. The older name of the place was Rath Cúl, the fort of the corner, and it lingers in the townland names Rath and Coole nearby.
