As the nearby ruins of Grosmont Castle (Castell Grysmwnt) attest, the village (formerly a township) owes much of its origins to its strategic position in the borderlands between England and Wales, and the church's history is no exception. There are claims that the church's construction was begun by Brian de Wallingford around 1180, and the work completed by a French architect employed by Queen consort Eleanor of Provence, but there is very little evidence in support of this. The only work in the church which seems to be of this date are the stiff-leaf carved capitals of the crossing arches; although almost entirely recut in the 19th century, their design has much in common with contemporary work at nearby Dore Abbey in Herefordshire, suggesting that this area of the building may have more ancient origins, perhaps forming part of a humbler structure which was later hugely expanded.

However, an origin for the remaining fabric of the building is more likely to be found in the early 13th century, when the castle was expanded by Hubert de Burgh, the Earl of Kent (who did the same at nearby Skenfrith), and the village grew into an important market town, which of course required a befitting church. The vast majority of the present building, built in red sandstone rubble, dates from this time, including the nave, aisles, transepts, and much of the chancel. This cruciform plan, ambitious for a country church, remains little changed to this day, with the exception of the southern Lady Chapel. This 13th century chapel was possibly built at the behest of Edmund Crouchback, Earl of Lancaster and son of King Henry III and Eleanor of Provence, and later came to be known as the Eleanor chapel due to this association. However, little is known of the chapel and it was demolished in the 19th century. Remarkably, the nave roof is also of the 13th century; 50 oak trees from the forest at Trevill were granted to the aforementioned Hubert de Burgh in 1227 for use at Grosmont, and 4 more were granted in 1240 specifically for repairs to the church. Recent dendrochronology work confirms that the nave roof is likely made from these very timbers, and, as such, cements its place as the oldest timber church roof in all of Wales.

The 14th century saw the addition of the north porch and impressive octagonal tower and spire, and hereafter, little building work was carried out until the 19th century. One exception to this is the fine west window with its Reticulated Decorated Gothic tracery, which dates from c.1340, though it may actually be a reused window from the great hall of the castle and have been inserted later. Another exception is the dormer window of c.1500 at the northeast end of the nave, designed to light the now vanished rood loft. A corresponding window on the south side has now vanished, presumably in the Victorian restoration. 

In the 19th century, John Pollard Seddon took it upon himself to restore the church, which was by then in a poor state of repair with abounding structural issues, not least in the tower. Seddon made up the latter half of the firm Prichard & Seddon, who acted as architects to the diocese of Llandaff, and as such seemed well qualified for the job, which was mostly financed by John E. W. Rolls (grandfather of Charles Rolls, co-founder of Rolls-Royce). Seddon's approach was essentially unique among Victorian restorers; instead of giving the entire church an overhaul which left the authentic medieval mingled in amongst the newly refurbished and invented Victorian, Seddon effectively entirely segregated the ancient and the modern, with the chancel and transepts receiving a very customary rebuilding and refurnishing in a rather stuffy and idiosyncratic Victorian style, but the nave being essentially left to its own devices, other than the stabilisation of the structure.

The chancel was almost entirely rebuilt between 1869 and 1879, with the altar being raised and the flagstones replaced by encaustic tiles, save the western portion of the north wall, whose early 13th century window arcades remain and were replicated on the south. The new east window replaced the 13th century triple lancet configuration. The transepts were not entirely rebuilt, but access to them from the nave (formerly permitted by their unusual westward expansions) was blocked in 1873-74 and the north transept gained a new east window while the south chapel's windows were all replaced. The most significant work carried out in this half of the church was the stabilisation of the crossing arches, failing under the weight of the added tower, which were successfully underpinned one by one and their rubble infill and foundations replaced in sturdy cement. A habitual vestry was also added to the south of the chancel in 1869, entirely replacing the Eleanor chapel.

As for the nave, Seddon screened it off from the rest of the building, which had been planned since 1822, in order to bring the congregation closer to the priest and choir; given the decline in the village's population since the medieval period, a nave of this size was hugely surplus to requirements and so I can get behind the reasoning here. This screening had the happy effect of leaving the nave as a time capsule, a window into the 13th century with its bare rubble walls, exposed ancient roof timbers (which may have been unthinkingly replaced had the nave been equally zealously restored), and floor paved with grave slabs. The screen itself is a fine piece of work, designed by Seddon and consisting of spacious wooden tracery filled in with clear glass. Seddon also stabilised the arcades which had begun to lean westwards, pushed by the weight of the tower, replaced a pair of square (possibly late 15th century) windows in the south wall with triple lancets, and removed much medieval plaster from the walls, of which only traces remain. This restoration is one of the more unusual I have come across; I am not particularly in love with the treatment of the chancel and Eleanor chapel, but the nave screening and excellent stabilisation work are to be commended for their ingenuity.

The information here has been taken variously from the the comprehensive church guide (booklet available from the church for a small fee, but absolutely worth every penny for the amount of detail included), and the Cadw listing.

The village of Grosmont is about as quintessential as a Marches village can get; a sleepy, quaint town surrounded by hills, overlooked by a castle ruin. The church lies downhill from the main road and castle but still reaches out from this dip in the landscape with its ambitious tower and spire, an uncommon sight in this region. The setting is quite lovely and easily appreciable as something beautiful.

The church is uncommonly entered from the north side, a side which has acquired some superstition nationwide due to its lack of sunlight, and north doorways are often found to have been blocked once they lost their processional function post-Reformation. However, Grosmont's church appears to always have been entered from the north, which makes sense given that the village and castle are both north of the church and it is natural to approach the church this way. Going through the porch will take you into the first half of the building: the ancient nave space. This is an incredibly atmospheric area, with scraped rubble walls and exposed roof timbers giving it a distinctly barn-like feel, but the grave slabs paving the floor solemnly remind you that this is a sacred place. There are next to no furnishings in the nave area and this has the effect of massively opening up the space and uniting the nave and aisles as one contiguous and airy unit. Despite this openness, the nave is quite dark, with the west window being relatively small compared to the remainder of the wall, and the lancet and dormer windows really having to battle against the gloom of this powerful space.

Going through the dividing screen, however, is a total shock to the senses. To pass through the screen is to step into a completely different world, moving from the ancient and open to the modern and used. This may as well be a totally different church, with Victorian Gothic furniture, glass, and whitewashed walls swamping the senses and hemming you in on all sides. I often say that the chancel appears to be another world, but nowhere is that more the case than here at Grosmont. Many of the more interesting artefacts are contained in this part of the church, however, so the ancient still bleeds through into this distinctly Victorian interior. Grosmont's church is undoubtedly a unique space among churches and makes clear the incredible distinction between authentic medieval fabric and its modern reinterpretation. One can only marvel at this dichotomy, united in one building and separated only by one, totally liminal screen. Whilst there may not be much to marvel at in the way of artefacts, the building itself must be savoured for the incredibly different way in which it encloses space.

At the southwestern end of the nave lies an enigma; a crudely carved, absolutely huge effigy to an unknown warrior. This likely dates from the 13th or 14th century and was never finished. The most often suggested person it was intended to commemorate is Henry of Grosmont, Duke of Lancaster, who was born in the nearby castle in c.1310. However, he died at Leicester Castle in 1361 and was buried in the now destroyed Church of the Annunciation of Our Lady of the Newarke (which rolls off the tongue exceptionally well), which does not seem to have been an unplanned interment, so what would his intended effigy be doing in Grosmont? Perhaps it was a presumption that Henry would be buried in his place of birth which prompted the initial creation of the effigy, and might explain its unfinished nature, but that is presuming that the effigy is intended to commemorate him at all. The fact of the matter is that the identity of the knight is unknown, and possibly never will be, hazy as the mists of time are.

The effigy itself is rough hewn and shows the knight recumbent in his armour, his blank shield to his left side and his hands clasped in prayer. A blobby sketch of the knight's face has also been etched on, and the entire monument is lacking enough detail that it is hard to tell whether its appearance is the result of its unfinished nature, the more rustic level of talent of the carver, or simply the wear sustained over seven centuries. Also unmissable is the sheer size of the effigy, hulking in the dark as it does. Were the effigy to be finished, it is likely that the subsequent carving would have sized it down a fair amount, but it is still undeniable that the commemorated would have been depicted almost certainly larger than life. One cannot help but wonder why the effigy was even kept; surely there would have been plenty of knights lining up to have the effigy recycled and completed to depict themselves given the proximity of such a strategic stronghold to the church. Regardless, the effigy lies incomplete, a monument only to our propensity to forget those who see themselves to be mighty.

When entering the chancel area, one must leave the world of mysterious, goliath knights behind, but the legacy of notable memorials remains steadfast. This portion of the church's example is located on the west wall of the south transept and takes the form of a large sepulchral slab, mounted here ex situ, and commemorates Charles William and his wife Joan (née Baker). Dated 1636, the memorial is carved in the distinctive local low relief style, further examples of which can be seen at Skenfrith and Llantilio Crossenny. The slab was moved to its present position after undergoing extensive conservation work in 2011.

Charles was the mayor of Grosmont in the early 17th century and also acted as Deputy Steward of the Duchy of Lancaster (which sounds like something of a non-job obfuscated by an exalted title!) and Joan was the daughter of William Baker, Steward to the Lord of Abergavenny (for which I will repeat my previous point). The couple had no children, and as such their estates passed to their inheritor, one Henry Gabb, whose name is also incised on the slab and dated 1708.

The memorial shows the couple in contemporary dress with their hands clasped in prayer. Charles appears to be standing, but Joan is almost certainly recumbent unless she had the ability to float. A staff lies next to Charles while a book lies next to Joan, and the pair are separated by a rustic Classical column of some description (perhaps Ionic? The capital is very crude). The much damaged inscription runs around the edge of the stone and additionally takes up a large rectangular space above the couple's heads, with this inscription being further surmounted by angels.
