The enclosure, measuring approximately 60 metres north to south and 53 metres east to west, is bounded by a limestone wall that holds within it memorials from the eighteenth and nineteenth centuries, the legible record of several generations of local burial practice pressed up against the much older fabric of a medieval ecclesiastical site.

The church here has a long and somewhat diminished history. It appears in the ecclesiastical taxation of the Diocese of Killaloe in 1302, a document that catalogued the parishes and their assessed values across the diocese, placing Knigh within a network of medieval church administration that stretched across the north Tipperary and Clare region. By the time of the Royal Visitation of 1615, a survey conducted to assess the state of Church of Ireland parishes following the Reformation, the building was already described as ruined and lacking a chancel, the chancel being the eastern section of a church typically reserved for the altar and clergy. That description, recorded by Murphy in 1914, suggests the site had already fallen out of active use well before the seventeenth century was out, left to accumulate later burials within its walls while the church itself crumbled quietly above the pasture.
