Part of the RC Parish of Windgap, in the Diocese of Ossary, the village's most noted landmark is St Niochlas' church of Kilmacoliver, built in 1885. The church itself underwent major renovation in the mid 70's, removing access to the upper level, installing a false ceiling and removing the bell and alter window on the alter wall. The alter window which was moved to a residence in Owning Co. Kilkenny, was returned to the church in the late 2000's and is now located as a window between the porch of the church and the main building. The bell has, since the renovation, been located at the main door of Windgap national school (the school bearing the same name as the church, St Nicholas'). Another noted landmark is the old school, now community center, which is located adjacent to the village church. The school, which during its use was divided into boys and girls, was damaged by a fire which destroyed the boys' side in the mid-20th century. The school was restored after the fire, but has since been used as a community center afer the schools' amalgamation into Windgap national school. Pre-historic landmarks of the village include a stone age burial ground which is situated on the peek of the Booley hills above the village. The site of the burial ground is reminiscent of a stone circle of which only the weathered remains are now visible. The ground is close to a "Newgrange" like structure called the "Cashal", which like Newgrange is noted for light passing through chambers only during the solstice.
