Summary

A slight univallate hillfort the NW of Theydon Bois Golf Course, lying at the highest point within Epping Forest and 3km to the NE from Loughton Camp (Atlas No. 3483). Sub-rectangular in form it encloses approximately 5ha. It occupies a ridge of sand and gravel which slopes gently to the SE at between 109-116m OD. The earthen bank of dump construction stands approximately 1.3-2.2m high and 13m wide with a counterscarp 0.4-1.0m high and 5m wide. The 7-10m wide flat-bottomed ditch is now silted up. A berm lies between the bank and ditch. Six breaks cut through the circuit, with only the one in the NW considered to be original, constructed as a stone revetted rectangular passage, possibly with inner and outer gates and approached by a causeway across the ditch. The bank terminals were revetted with coursed stone blocks. The head of a small valley lies within the interior in the SE from which a stream breaches the bank, although augering suggests the bank was originally complete. No internal occupation has been identified. The site has been dated from pottery recovered from the ditch, to the second half of first millennium BC with some reuse in the later Iron Age. The interior is crossed by medieval tracks and it was quarried for sand and gravel. Wild Service trees, a relict species, lie in the vicinity of the enclosure and this has been interpreted as the area still being wooded when the hillfort was constructed. Gold coins of Tasciovanus and Cunobelin were discovered by a metal detectorist in the vicinity of the hillfort. There are also unverified reports of finds of a spearhead, pottery, coin and a knife. Small amounts of worked flint including a barbed and tanged arrowhead was recovered from the ditch fills, suggesting 2nd millennium BC origins. Excavated by Pitt Rivers in 1881, with further investigations in 1933, 1956, 1958 and 1968 concentrated mainly on the ramparts with only a small area of the interior investigated (Alexander et. al. 1978). A resistance survey of 1.6ha was undertaken in 1958. Recorded on 1870-72, 1:2,500 OS mapping.

Boundary

The hillfort lies at the junction of a number of parish boundaries. The boundary between Epping Upland and Waltham Abbey runs NW-SE through the enclosure. The parish boundary between Epping Upland and Theydon Bois lies 150m to the SE. The parish boundary between Waltham Abbey and Theydon Bois lies to the 100m to the SW.

Boundary Type:  Parish/Townland


Dating Evidence

Small amounts of worked flint including a barbed and tanged arrowhead were recovered from the ditch fills, suggesting 2nd millennium BC origins. The main works are dated by excavated pottery the the second half of the first millennium with use in the later Iron Age
