Old Copse, on the edge of Sonning Common, is believed to be an ancient, semi-natural woodland. The majority of the wood is owned by the Woodland Trust.
In 2001, a four-sided enclosure was found in the southern section of the wood measuring 84 by 100 metres. It is formed by a large ditch 8-10 metres wide and about a metre deep, with internal and external banks in places. Experts are unsure of the nature of this enclosure. One local expert has discounted ancient Neolithic earthworks, a Roman marching camp and a medieval game enclosure, while another suggests that the alignment and form of the banks and ditches could suggest an older feature, perhaps dating back to Romano-British times.
The cache is a camo-ed micro, placed on a public footpath. There is only room for a log-sheet, so please bring your own pen/pencil.
