Roman West Sussex

The quickest way to understand Roman West Sussex is to focus on the hub-and-spoke network centred on Chichester, then trace the roads and settlement sites that survive today. The county’s Roman story is not a single monument but a landscape of roads, walls, villas, and a palace, all connected by a road system built from the 1st century AD. The most complete single site is Fishbourne Roman Palace (constructed c. 75-100 AD, discovered in 1960), which holds the largest known in-situ mosaic north of the Alps and is run by the Sussex Archaeological Society. The palace is open seasonally from March to October [annual; verify exact dates at the Sussex Archaeological Society website]. The practical question for a visitor is: which Roman places in West Sussex can I see today, and how do I verify access before I go?

The Chichester Base: Walls, Amphitheatre, and Street Plan

Chichester was the Roman civitas capital of the Regni, known as Noviomagus Reginorum. Its most visible Roman legacy is the city wall circuit, built around 200 AD, which runs for 2.5 km (1.5 miles) and once had four gates (North, South, East, West). The walls are free to walk and are always accessible. The Roman amphitheatre, located west of the city centre near Avenue de Chartres (grid ref. SU 861 048), had an estimated capacity of 8,000. Today the site is a grassed oval in a public park; there are no standing remains above ground, but the earthwork is clear. The street plan of the city centre still follows the Roman grid in part, especially the line of the main north, south axis.

Decision rule: If you have half a day, walk the wall circuit (allow 45 minutes at a steady pace) and then visit the amphitheatre earthwork. For the best context, follow this with Fishbourne Roman Palace (see below). Verify the wall’s condition and any temporary closures via the Chichester District Council website before setting out.

Fishbourne Roman Palace: The Anchor Site

Fishbourne Roman Palace (grid ref. SU 826 047) is the single most important Roman site in West Sussex. It was a high-status residence, not a military fort, and its surviving mosaics are the main draw. The site is operated by the Sussex Archaeological Society and is open March to October [annual]. An admission charge applies [verify current fee at the Sussex Archaeological Society website]. The palace is about 2 km west of Chichester city centre, accessible by a flat walk, cycle, or short bus ride.

Checklist for visiting Fishbourne: - Confirm opening dates and times on the Sussex Archaeological Society website (the season is March, October, but specific days and hours vary). - Check for pre-booked time slots; the site can reach capacity on school-holiday weekdays. - The site has a cafe and toilets, but verify seasonal availability on the official site. - Parking is on-site, but capacity is limited; if the car park is full, there is no overflow.

The Road Network: Stane Street and Others

Roman roads radiated from Chichester to London (Stane Street), Silchester, Winchester, Lewes, Portslade, and multiple local settlements including Bignor, Fishbourne, Selsey, Arundel, Pulborough, Midhurst, Petworth, Horsham, and Crawley. Stane Street (London to Chichester) was built in the 1st century AD and runs 91 km (57 miles). In West Sussex, its course is partly followed by modern roads and partly by footpaths. The most accessible section for walkers is the stretch through the South Downs near Bignor, where the Roman agger (raised bank) can still be seen in places.

How to trace a Roman road today: - Use the Ordnance Survey 1:25,000 map (Explorer series) and look for the dashed line marked “Roman road” or the name “Stane Street”. The South Downs National Park Authority publishes a free downloadable Roman roads leaflet [verify on the SDNPA website]. - Walk the section from Bignor Roman Villa north towards the A285; the route is a public footpath across arable fields. Be prepared for muddy conditions after rain, chalk turns slippery. - Do not rely on mobile phone signal in the downland combes; download the map before you go.

Bignor Roman Villa: Mosaics in a Rural Setting

Bignor Roman Villa (grid ref. SU 988 147) contains a remarkable set of 4th‑century AD mosaics, protected under a thatched roof. It is also operated by the Sussex Archaeological Society and has the same March, October season [annual]. An admission charge applies [verify at the Sussex Archaeological Society website]. The villa is about 11 km northeast of Chichester, off the A285.

Decision rule for choosing between Fishbourne and Bignor: If you want the largest site and a museum context, go to Fishbourne. If you want to see mosaics in their original rural setting with a thatched cover and a quieter atmosphere, go to Bignor. Both are worth visiting, but a single day trip can include both if you drive (allow 20 minutes between them) or if you take a taxi from Chichester.

Roman Sites on the South Downs Way

The South Downs Way National Trail runs 100 miles through the national park, and its West Sussex sections pass near several Roman sites. The most notable is Bignor Roman Villa, which lies about 1 km east of the trail. There are also sections of Stane Street that align with the trail near Cocking. The South Downs National Park Authority (SDNPA) provides a downloadable guide to archaeological sites along the trail [verify on the SDNPA website].

Method for walkers: Before setting out, download the SDNPA’s “Roman West Sussex” walk leaflet. It describes a 10 km circular walk from Bignor that includes the villa, sections of Stane Street, and downland views. The walk has about 150 m of elevation gain and is not pushchair-friendly due to stiles and uneven chalk surfaces.

Arundel: Roman River Crossing

The Roman road from Chichester to Arundel crossed the River Arun near the present-day town. No visible Roman structure remains above ground in Arundel itself, but the line of the road is traceable on maps. The Arundel Castle and Arundel Wetland Centre (WWT) are medieval and modern respectively, not Roman. The Roman interest lies in the route: the road from Chichester to Arundel ran roughly along the line of the modern A27 and then north to the river crossing.

Practical note: If you are visiting Arundel for its Roman context, you will be viewing a landscape rather than a monument. The best approach is to park at the Wetland Centre car park (pay and display) and walk south along the river path to the approximate crossing point. Verify the route on the OS map before you go.

Worthing and the Coast: Roman Ports

The Roman road from Chichester to Portslade ran along the coastal plain, passing near modern Worthing. No Roman buildings are visible in Worthing, but the line of the road is preserved in field boundaries and occasional footpaths. The coast at Shoreham-by-Sea has a Norman church but no Roman remains above ground. The Roman harbour at Chichester Harbour (now a tidal AONB) was used for trade but has no surviving structures.

Checklist for coastal Roman exploration: - Use the OS map to trace the Chichester, Portslade road (marked as “Roman road” on some editions). - The best section to walk is the footpath between Worthing and Lancing, which follows the approximate line. - Tide times matter if you walk near Chichester Harbour. Check tide tables from the Met Office or the harbour authority before setting out.

Crawley and Horsham: Roman Roads Inland

The Roman road from Chichester to London (Stane Street) passes east of Horsham and west of Crawley. The modern A29 and A24 follow its general line in places, but the original agger is lost under tarmac and development. No Roman buildings are visible in either town. The interest is historical: Stane Street was the main artery connecting the civitas capital to Londinium.

Decision rule for inland visitors: If you are based in Crawley or Horsham and want to see a Roman site, the nearest accessible location is Bignor Roman Villa (about 25 km from Horsham, 35 km from Crawley). Alternatively, drive to the South Downs Way at Cocking and walk the Stane Street section.

How to Verify Access Before You Go

Every Roman site in West Sussex is operated by a named organisation with published seasonal hours and fees. The following steps will save you a wasted journey:

1. Go to the operator’s website, not a third-party listing. For Fishbourne and Bignor, use the Sussex Archaeological Society site. For the South Downs Way sections, use the South Downs National Park Authority site. For the Chichester walls and amphitheatre, use the Chichester District Council site.
2. Check the “plan your visit” page for opening months, days, and any pre-booking requirement. The season is March, October for the villa and palace, but individual days may vary.
3. Check for planned closures due to conservation work or staff shortages. These are not always announced on third-party sites.
4. Verify parking and toilet availability on the official site. The official car park capacity figure is a theoretical maximum; on sunny weekends, both Fishbourne and Bignor car parks can fill by 11 am.
5. If walking a Roman road section, download the OS map or the SDNPA walk leaflet. Do not rely on mobile phone signal in the downland combes.
