Herefordshire Council's archaeological team are carrying out some more work at Credenhill hill fort this summer.
Peter Dorling, senior project archaeologist, who led the dig at the hill fort last summer, will again be in charge of the excavations which will be carried out until the end of July.
Students from Cardiff and Hull University will be helping with work on three areas of the historic hill fort.
First, they will look at re-opening some of the areas which were explored by Stan Stanford in the 1950s and see if modern techniques can come up with any different conclusions to what he found.
Then they will be looking through the area of a defensive rampart where it has already been disturbed by a culvert.
Thirdly, they will be looking at in more detail at an area that was examined last year and produced evidence of Roman activity on the site.
General work will also be carried out to look at the effect of trees on the site.
The Heritage Lottery Fund has given the Woodland Trust a grant to fund their management work at the Credenhill hill fort.
Eventually, the Woodland Trust wants to clear fell all soft wood in the northern half of the site so this can be managed as grassland.
Open days will be held at the hill fort on July 5 and 6 for members of the public to see the latest work being carried out.
Two walks/visits will be held each day, one at 10am and the other at 2pm. Numbers will be restricted and bookings should be made by contacting Jacky Denovan on 01432 260470.
The Environment Agency has carried out a LIDAR (Light Detection and Ranging) survey of the hill fort which, through using an airborne mapping technique, will help reveal the contours of the hill fort site, much of which is covered by trees.
Results from the LIDAR survey are due soon and will help to inform future archaeological work at the site.
