Reading the Building Like a Document

Every parish church in Britain is a document written in stone, and like any document it has been edited, annotated and occasionally scribbled over. Most of our churches were built between the eleventh and sixteenth centuries, then repaired, reordered and re-pewed for another four hundred years after that. The good news is that you do not need a degree in architectural history to make sense of them. Learn half a dozen features — a font, an arch, a screen, a window — and a stroll round the churchyard becomes a genuinely absorbing detective story.

Start with a simple rule: churches tend to grow outwards and upwards over time. The nave and chancel are usually the oldest parts, while towers, porches, side chapels and big windows are often later additions. Norman work generally survives low down in the walls, and pointed arches replaced round ones from about 1190 onwards. Do be cautious, though — round arches were still built long after 1200, and older openings were sometimes "sharpened" to look more fashionable. Nothing in a parish church is ever quite as tidy as the textbooks suggest.

The Font: Baptism at the Door

If you only examine one fitting, make it the font. Fonts are heavy, awkward to move and liturgically essential, so they were rarely replaced — which makes them unusually reliable evidence. A Norman font (roughly 1066 to 1200) is often a stout tub or cube cut from a single block, standing on a later plinth. Look for scalloped capitals, zigzag chevron ornament, cable moulding and chip-carved geometric panels. Many retain a lead lining with a lockable lid, often a seventeenth-century addition.

Some carry figure carving: the Seven Sacraments, the Labours of the Months, a Green Man peering from the foliage. All of it was once painted, and you were meant to read it in the gloom of a nave lit only by candles and a few small windows. You will usually find the font at the back of the nave near the south door, where baptisms traditionally took place — entry into the church mirroring entry into the Christian life.

Walls, Windows and the Arrival of Gothic

Round arch means Romanesque; pointed arch means Gothic. It is a rough guide, but a useful one. The Early English style, from about 1190, brought tall, narrow lancet windows grouped in twos and threes, plate tracery and stiff-leaf carving. The Decorated style of roughly 1250 to 1350 introduced flowing, curvilinear tracery, ogee arches and increasingly rich ornament. Then came Perpendicular, from about 1350 to the Reformation — the great British speciality, with strong vertical mullions, enormous windows, four-centred arches, fan vaults and battlemented parapets.

The wall fabric tells its own story. Herringbone masonry, reused Roman brick and wide, irregular mortar joints point to the eleventh or twelfth century. Knapped flint flushwork, with its chequered patterns, is a hallmark of late medieval East Anglia. Also look for blocked doorways, straight joints in the stonework where a wall was extended, and a chancel arch that plainly does not match the walls around it.

The Rood Screen and the Lost Medieval Interior

Our churches were once far more colourful and crowded than they are now. The rood screen divided the nave, where the people stood, from the chancel, the priest's domain. Above it ran a loft carrying the great rood — a cross with figures of Christ, Mary and John — and a stair in the wall gave access to it. Most lofts and roods were removed in the sixteenth century, but many screens survive, particularly in Devon, Norfolk and Suffolk.

Examine the carved tracery heads, the cusped openings, the wainscot panels that once showed painted saints, and the foliage-carved cornice. A stub of stone stair in the wall is the rood stair. Other medieval fittings worth hunting for include the piscina, a small basin in the chancel south wall for washing the sacred vessels, and the sedilia, seats for the clergy beside it. An aumbry in the north wall was a cupboard for the reserved sacrament, and a squint, or hagioscope, let a worshipper in a side aisle glimpse the mass.

Small Clues in Odd Places

Scratch dials, also called mass dials, are faint circles with radiating lines cut into south-facing jamb stones — simple sundials that told a priest when to ring for services. Consecration crosses, usually marked with a circle, survive on some walls. Graffiti, from merchant's marks to initials and ships, crowds the pillars and tower stairs of churches near ports. Bench ends, often carved with poppy heads or animals, are usually fifteenth or sixteenth century, though many were replaced in Victorian restorations. A tower that looks strangely detached from the nave may simply be earlier, or later, than the rest.

A Field Guide for Your Next Visit

Take a slow circuit before you go inside, and keep a few questions in mind:

• Font: square or round? Chevron or scalloped carving? Lead-lined and locked?
• Arches: round or pointed, and does the chancel arch match the walls?
• Windows: lancets, flowing tracery or vertical Perpendicular mullions?
• Screen: any carved tracery, painted panels or a rood stair nearby?
• Chancel: piscina, sedilia, aumbry or squint?
• Walls: herringbone stone, straight joints, blocked openings, scratch dials, graffiti?

Finally, remember these are living buildings rather than museums. Check opening times before travelling, sign the visitors' book, avoid touching wall paintings and brasses, and leave a donation. A good church guide, often a modest booklet by the door, will tell you far more than any general book — and the churchwardens usually enjoy being asked.
