Buckland Rings is the site of an Iron Age hill fort in the town of Lymington, Hampshire. Today, the mounds and dykes around the outside which once constituted its defences are still clearly visible, although the outer bank lies under the road on the west side, and on the south-east it is nearly ploughed-out. Excavations of the inner and middle ramparts in 1935 revealed that they were of wall-and-fill construction, retained at the front by upright timber beams and walls of cut and laid turf. The entrance, which lies on the east side, was also excavated revealing a long entrance passage and the postholes for a pair of stout gateposts.
