The Church of St Illtyd, Mamhilad, Monmouthshire, Wales, is a parish church with its origins in the 11th century. Renovations took place in the 19th century and again in 1999–2000. It is a Grade II* listed building and an active parish church.
The church dates from the medieval period but the building fabric cannot be dated with certainty. Mention of the church is made in a record of 1100. The existing features are late medieval, or of the restoration undertaken by John Prichard and John Pollard Seddon in 1864–1865. A further restoration took place in 1999–2000. The church remains an active church in the parish of Mamhilad with Monkswood with Glascoed.[1]
The church is built of Old Red Sandstone rubble. The style of the existing fabric is Perpendicular. The church comprises a nave, chancel, two porches and a bellcote. Cadw describes the rood loft as a "great rarity" and the listing record for the church's Grade II* designation notes the "extremely fine and rare rood-loft".
