For over 800 years the castle and church have stood 100 metres apart from each other on the Welsh bank of the River Monnow at the crossing in Skenfrith.
When the Norman Marcher Lord Hubert de Burgh was first Lord of Skenfrith, he extended the castle and its defences and at the same time enlarged the church whose founding document is dated from 1207.
It is a large church with seven roofs and eight windows original to its building. The north aisle was constructed from large sandstone blocks with generous five windows was built out within the next century and the south aisle added about 50 years later. The vestry was probably added in C16 and the south porch post Reformation. At the Restoration, work was done to repair the church which was recorded in the south aisle and on the font. No major remodelling of the church was done between 1663 and 1909.
