[3][4] The church and adjacent graveyard are located on Quill Street, in the eastern suburbs of Tralee.

[5] It is believed that a ringfort or embanked enclosure was built here first (Rath Mhaighe Teas, "fort of the southern plain").

[7] The west gable and part of the nave walls belong to this earlier construction; the rest of the church is later.

Based on its Primitive Irish grammar, the inscription is estimated to be from around AD 550–600.

[9] The stone is of fine purple sandstone (145 × 34 × 20 cm), with the inscription [A]NM SILLANN MAQ VATTILLOGG ("name of Sílán son of Fáithloga").
