Collegiate Church of SS Peter & Paul, Medieval church and national monument in Kilmallock, Ireland.

The Collegiate Church of St Peter and St Paul stands on the south bank of the River Loobagh, north of Kilmallock's main street. It has a nave and chancel with a south transept, three aisles and a north transept, plus a 13th-century doorway in the south wall. The chancel holds five lancet windows in embrasure, and a tower in the nave's northwest corner incorporates the stump of an early monastery round tower.

The church was completed by 1241, probably on the site of a monastery founded by Mocheallóg around AD 600, of which a round tower stump survives in the northwest tower. It was dedicated to Peter and Paul in 1410, and in 1420 Maurice Fitzgerald substantially altered the nave and transept. It became a collegiate church in the 15th century, was partly destroyed by Cromwell and was roofless by 1657, remaining in Church of Ireland use until a 1935 fire.

The church was dedicated to Saints Peter and Paul in 1410 and became a collegiate church in the 15th century, served by a college of priests. In the south transept, carved tombs from the 16th century remain in place, and a 13th-century doorway survives in the south wall.

The church stands on the south bank of the River Loobagh, north of Kilmallock's main street. Look for the 13th-century doorway in the south wall and the five lancet windows set in an embrasure in the chancel. The nave's northwest tower holds the stump of the early monastery's round tower.

The northwest tower of the nave contains the stump of a round tower from the early monastery said to have been founded by Mocheallóg around AD 600. Most visitors pass it without noticing that the medieval church was built over an older monastic site.
