Reading the Landscape: Why Roman Roads Still Look Roman

Roman surveyors worked from high ground and aimed at a fixed point on the horizon. The result is a network of roads that ignores hills, hollows and the natural curve of the land. Two thousand years later, that stubbornness is exactly what makes them easy to spot. Stand on any ridge in lowland England and look for a hedge, a parish boundary or a minor lane running arrow-straight for a mile or more, with no regard at all for the contours beneath it.

Underfoot, a good Roman road was a serious piece of engineering. A trench was dug, then filled in layers: a foundation of large stones, a bedding of smaller rubble, a core of compacted gravel or cement, and finally a cambered surface that shed water into the ditches on either side. The metalled surface was usually between four and six metres wide; the whole corridor, ditches included, could be three or four times that.

Place names are your friend here. Anything containing street, strat, stret or stone in a parish name often marks the line — Stretton, Stratton, Stretford, Stone Street. Portway and Akeman Street are other reliable hints. If a footpath runs dead straight for half a mile between two villages and the hedges are wider apart than usual, you are probably walking on one.

Roman Roads You Can Actually Walk

Many stretches are now motor roads, but a surprising number survive as lanes, bridleways and field paths. These are the ones worth planning a walk around.

• Peddars Way, Norfolk — a 46-mile National Trail running from the coast near Holme-next-the-Sea to Knettishall Heath. It follows the Roman road for most of its length, and the straight sections across the Brecks are wonderfully atmospheric.
• The Fosse Way — Exeter to Lincoln, laid out in the years just after the conquest. Between Bath and Lincoln it survives mainly as quiet lanes and field boundaries, and there is a fine straight run in the fields around Bingham in Nottinghamshire.
• Ermine Street — London to York by way of Lincoln. North of Lincoln, short lengths survive as a minor lane threading between fields, while part of the modern road still sits on the original alignment.
• Stane Street — London to Chichester. The Sussex stretch is the best preserved, including a clear run through the fields and woods just south of Bignor Roman Villa.

Inside a Villa: Mosaics, Baths and Warm Floors

What usually survives of a Roman villa is the ground plan: a corridor, a row of rooms, and a bath suite at one end. Look for the tell-tale stoke hole and the stacks of small square pillars — pilae — that once carried a suspended floor. That is a hypocaust, the Roman version of underfloor heating, and hot gases from a wood fire circulated beneath the rooms and up through hollow box tiles in the walls.

The bathing sequence is worth learning, because it explains the room plan at almost every site: you undressed in the apodyterium, warmed up in the tepidarium, sweated in the caldarium, then plunged into the cold frigidarium or an outdoor pool. Mosaic floors were laid by travelling workshops working from pattern books, which is why a geometric border at one villa often turns up, mirrored, a hundred miles away.

Four Villas Worth the Detour

• Bignor, West Sussex — some of the finest mosaics in Britain, including a long corridor floor with Ganymede and the eagle. Set in open downland, with the road that served it running nearby.
• Chedworth, Gloucestershire — a Cotswold valley villa with a complete bath house and a remarkable water shrine. The walk down through the woods to the site is half the pleasure.
• Fishbourne, West Sussex — an enormous palace, probably built for a pro-Roman client king. The Cupid on a dolphin mosaic is the star, and the formal garden replants species the Romans would have known.
• Brading, Isle of Wight — a small villa with an outsized collection of mosaics, several still in their original positions under cover.

Two more for a longer trip: Lullingstone in Kent, with its Chi-Rho wall painting from a Christian house church, and Great Witcombe in Gloucestershire, a hillside villa with an unusually elaborate bath wing.

Museums That Fill in the Gaps

Villas give you rooms; museums give you the objects that made those rooms work — glass, samian ware, hairpins, gaming counters, writing tablets. The Corinium Museum in Cirencester is the best introduction to Romano-British domestic life anywhere in the country, and Verulamium Museum at St Albans sits beside the remains of a Roman town. The Yorkshire Museum in York, the Jewry Wall in Leicester and the Grosvenor Museum in Chester all repay an hour. For forts and frontier life, the museums along Hadrian's Wall are unbeatable, and the site at Vindolanda is famous for its preservation.

If you want a whole Roman town without a modern town on top, go to Silchester in Hampshire. The walls, gates and amphitheatre survive in open fields, and you can walk the full circuit in an afternoon.

Practical Notes Before You Go

• Most villas and open-air sites are seasonal, typically Easter to the end of October, and several close on Mondays and Tuesdays. Check opening days before a long drive.
• Wear boots. Even the well-managed sites involve grass, mud and uneven mosaic floors under cover.
• Satnav postcodes for rural sites often drop you at a farm gate or a field entrance. Look for brown tourist signs once you are within a mile.
• Take a picnic and cash for small cafés and honesty boxes; some rural sites have very limited facilities.
• Photograph the mosaic floors without flash, and never walk on them, however tempting the pattern.
• Combine a villa with a nearby stretch of road on foot. Seeing the two together — the house and the highway that supplied it — is when Roman Britain stops being a school subject and becomes a place you can picture.
