This post looks at the walk around the hillfort and its ramparts, with its section of Wat’s Dyke at its foot, and lovely views across the landscape. Parking details are at the end.
This makes a great day trip with a visit to the Whittington Castle (see Wikipedia), only 2.5km away to the east, or the market town of Oswestry just to the south (see the official Visit Oswestry site here). It is free of charge to visit at any time, with one main parking area and a small lay-by. See Visiting details at the end.
Old Oswestry hillfort is a magnificent archaeological site and local landmark dating to the 4th to 7th centuries BC during the Iron Age with terrific views over the surrounding lowland landscape. Seen from above the pentagonal shape is particularly distinctive, and you notice this whilst walking, as it is one of the few hillforts at which you reach corners. It is also undulating – as you walk around the top you will notice that they path goes up and down, never at all steeply but just enough to draw attention to the varying levels. If you keep looking across the plateau you will see that this too is undulating; sometimes you can see across it but at other times you can’t. It is one of the most impressive and least-understood hillforts in the country, excavated only twice with sample trenches, with much more knowledge remaining to be discovered.
In April there are bluebells, celandines and wood anemones, and to keep the scrub down there are small herds of black sheep (Soay and Hebridean crosses) roaming the banks and ditches. On my visit this August, just a few days ago, the long-term drought had left everything incredibly parched, and the plateau grass had died off. Some of the young trees and shrubs were in fruit with red hawthorn berries, blackberries and dark purple alder berries. There had obviously been rosebay willowherb recently in flower, with its fluffy seeds catching the sun, and some gigantic thistles had recently gone over. Otherwise, it was the bracken that was winning the fight against the drought, in spite of a fine herd of attractive black sheep.
The site of Old Oswestry is built on a hill of clay, sands, gravels and mixed boulders left behind after the retreat of the last glacier, the whole thing lying on a bed of glacial clay. You can see boulders underfoot as you walk around the perimeter of the plateau. Old Oswestry is the largest of three similar hillocks, one of which is immediately visible to the south. The hillfort was excavated in 1939 and 1940 with seven trenches cut mainly across the ramparts, followed 80 years by a small excavation of three trenches in 2021 and 2022, again across the ramparts. The interior has never been subject to excavation.
The earliest known occupants used the hillfort during the Neolithic, and left behind two polished stone axes and a set of worked stone tools. The story of the archaeology of the Iron Age hillfort is complicated, but in essence it began with two banks that supported ramparts (defences built of stone), separated from each other by a ditch. The first pair of banks and ditches followed the natural line of the hill, only interrupted by two entrances, on the east and west sides. Over the 300 years that the hillfort remained in use, additional banks and ditches were added, in a less straight forward arrangement, causing the entrances to become corridors with banks along their sides. In total, there are two banks on the eastern side, five on the southern side, four on the south and seven on the west where a complex of hollowed out depressions were added either side of the western entrance. To date it is not known what the hollows were used for and they remain unique in Britain. There are photos of them below.

The hillfort was incorporated by Wat’s Dyke, which arrives at the hillfort’s southern corner, and departs at its northern end, using the hillfort’s presence as a component of the linear boundary that extends over a 60 km (37 mile) stretch of the Welsh border built in the 8th or 9th century AD. It begins in Maesbury, just south of Oswestry and extends all the way to Basingwerk, near Holywell, on the north Wales coast, roughly parallel to Offa’s Dyke, but much shorter. Although its purpose is currently a matter of speculation, it is thought to mark the border of Mercia in the west, and to be both a defensive and a symbolic structure, marking differences is political allegiance and administrative systems. There is only one small part of it visible at Old Oswestry, at the southwest corner, but the line of the Dyke is marked by a line of hedgerow and trees that heads north from the hillfort.

In the LiDAR image of Old Oswestry to the right, Wat’s Dyke can be seen at the bottom left, where it meets the corner on a perpendicular on the southern side and extends from northeast corner of the hillfort, both visible as a shaded bank leading into and out of the hillfort. The builders were obviously great pragmatists, making good use of a natural barrier in the landscape!
During the First World War, the interior of the hillfort enclosure was used for military training purposes, including the digging of practice trenches and setting off mortars and other explosive devices that left small craters in the top. Marks of both the trenches and the craters are visible in some aerial photographs, and are visible in the LiDAR image right (click to expand).
The photographs are a mixture from April 2025 and August 2026, showing the difference between the well-watered spring and the long-term drought of 2026.
From the bottom of the west entrance there is a shallow slope, with wide wood-framed stone steps to avoid mud slippage, leading up to the plateau. Here, there is a walk that follows the circumference of the hillfort.

East side of the top of the hillfort. Note that this photograph was taken in April 2025; in August 2026 the plateau was completely parched, and a light yellow colour as in some of the photographs below.
The middle of the interior is fenced off for pasture most of the way round, although you can enter it at the eastern entrance, where you also get a good sense of how undulating the plateau actually is, even though it looks completely flat in aerial photographs. At this point, as with many others, you cannot see from one side of the enclosed space to the other. Walking to the highest point of the plateau from the eastern entrance, up a slight slope, gives you panoramic views.
The ramparts and ditches can all be explored freely, and these give an excellent idea, even after centuries of erosion, of the scale of the construction work that made up the site. All of the rampart banks are so magnificently high that if you stand in the ditches, all you can see is the walls of the banks either side of you. It is in the ditches and on the side of banks, rather than along the plateau itself, that most of the wild flowers are to be found.

The hollows at the west end are reached most easily from a black metal kissing gate on the north side (left, going up) on the slope from the western entrance. This lets onto a single track footpath that passes at the bottom of the hollows and lets you get a sense of the scale of them, which is impressive. The hollows on the other side of the footpath can also been seen, but are much smaller. A footpath actually goes across the middle of them, but they are best seen from the second (looking down) or third ramparts (looking back).

One of the ponds or cells that you can see in the illustration at the top of the page, to the left of the west entrance as you go uphill, in April 2025. This was dry in the drought conditions of August 2026, but some of the hollows still had marsh plants at their edges.

The hillfort itself is dramatic and breathtaking, but the surrounding landscape also bears unmistakeable signs of Oswestry’s heritage, whilst beneath the fields there may well be more of the area’s prehistory to uncover. The hillfort used to part of the Park Hall estate, which once had one of England’s most impressive Tudor houses at its core before it tragically burned down in 1918. The Oldport Farm immediately below the hillfort on its southeastern side dates at least to the 17th century, and perhaps earlier, and the fields retain the imprint of much earlier agricultural heritage. During the First World War both the centre of the hillfort and other places in the vicinity, was used for digging practice trenches, both a chilling and touching reminder of the realities of the war. A Prisoner of War Camp and cemetery were both established nearby. There are even glimpses of the impact of the Industrial Revolution from the top of the hillfort, with the 19th century railway and Thomas Telford’s A5.
If you are looking for a great place for a short walk that focuses on a splendidly impressive and nationally important site, this should not be missed. The walk can be extended via other footpaths, or can be combined with a visit to Oswestry itself, which is a very attractive market town. You can download the Visit Oswestry’s Heritage Trail here.
The site was owned by Lord Harlech until 1946 when he handed it over to the state, and it is now the responsibility of English Heritage.

Visiting

The site is managed by English Heritage and it is free of charge to visit at any time, with one main parking area a five minute walk away from the hillfort, and a small lay-by. There is brown heritage signage from the A5, which takes you through a residential area to the Gatacre Playing Field car park where there is plenty of parking (What3Words ///spray.funky.tasters). There is also a layby with room for four or five cars. Both parking areas are shown on the map produced by the Old Oswestry Hillfort website.

I always park at the Gatacre car park because there is always plenty of room and it is only a five minute walk from the hillfort’s west entrance (the main access route to the hillfort). The route to the hillfort is all on the flat, along a metalled path and a small, very quiet lane.
If it hasn’t been raining, there is an even shorter route if you use the footpath (Oswald’s Way) from just beyond the car park to cut across the field – this was a gorgeous vista of sunflowers in August 2026, and would probably be even more sunflower-intensive in years that have had a bit of rainfall.
There are no facilities at the hillfort of any description, but there are plenty within Oswestry itself, only a short drive (less than two miles / 3.5km) from the site, or at Whittington Castle to the east.
The west entrance is a long, shallow slope now provided with long wood-framed steps lined with stone to protect visitors from muddy conditions, that leads up to the top. At the top, there is a footpath all around the plateau. The western and eastern entrances also offer access via gates and footpaths to the lower banks and ditches as well as the puzzling hollows that flank the west entrance. Note that sheep roam the banks and ditches, so gates must be closed and dogs must be kept on leads.
Although the entire plateau walk is a nice easy stroll all the way around, well-worn by dog walkers, some of the lower ramparts are more challenging. Most of the hillfort walks along banks and ditches are very easy to access on the south and west sides, but bracken can be a perpetual problem on some of the ramparts and ditches beneath the plateau on the north and east sides of the hillfort, particularly in the summer. It seriously impedes passage, as well as potentially doing significant damage to archaeological deposits, whilst its density eliminates other species, significantly reducing biodiversity. Love it or hate it, one has to admire the tenacity of bracken under such extreme conditions. Both volunteer work and sheep are combining to reduce the impact of such invasive species, managing the site for the benefit of biodiversity, the archaeology and visitors. If you find one of the rampart or ditch walks a bit of a struggle, there are plenty of others to try.
There are plenty of well thought out information signs along the course of the west entrance as well as on the footpath around the top, providing details about the archaeology and history of the site.
The walk can be extended via other footpaths. For example the diagonal route across the field from the car park to the hillfort’s west entrance is part of Oswald’s Trail, a 12 mile / 13 km circular walk about which you can read more on the Shropshire’s Great Outdoors website. Or it can be combined with a visit to Oswestry itself, which is a very attractive market town. You can download the Visit Oswestry’s Heritage Trail here.
