Known variously as Kill Church, Teampull na Cille, and Kyle, the building sits roughly at the centre of its graveyard, surrounded by rough meadow, with the Moorstown towerhouse and its bawn visible about 500 metres uphill to the north-north-east. A bawn is the defensive enclosure that typically surrounds an Irish tower house, and its presence here, in clear line of sight from the church, hints at the kind of layered occupation that characterises this part of Tipperary.

The church itself is a rectangular limestone rubble structure, aligned roughly east to west and measuring 14 metres along that axis internally. Its walls still stand to between 2.2 and 4 metres, and the east gable retains a pointed single-light window as well as a slight base-batter, a deliberate outward thickening at the base of the wall intended to add stability. A flat-headed single-light window survives at the east end of the south wall, and the remains of a third window are visible on the north side, though much of the fabric is now obscured by ivy. The name Kyle, used by the historian Power in 1907, carries real historical weight: he noted that the site was a very important and early church, with an allusion to it found in a tenth-century life of St Declan of Ardmore. The scholar Ó Cearbhaill, writing in 2007, connected the site to the placename Cill Bhaile na Móna, meaning the church of the townland of the bogland. Around 1840, the building had been closed up and repurposed as a private burial place for the Perry family of nearby Woodrooff. Three nineteenth-century altar tombs occupy the east end of the interior, and a single headstone dated to the 1730s represents an earlier phase of use.
