Close by but now apparently dried up, Pastscape records the site of "St Boniface Wishing Well" (SZ 5676878118):
"St. Boniface Wishing Well", a spring formerly much venerated, especially by seamen, because an impervious stratum caused it to rise high up on the side of a chalk down.
From "Undercliff of the IOW", 1911, 118-9. (J.L. Whitehead)
From Ward Lock's Illustrated Guidebook:
The Wishing Well is interesting to the geologist on account of its unusual height, and to the superstitious from the reverence formerly paid to it on account of a popular belief that if one achieved the difficult feat of climbing to the spring without looking backward, any three wishes formed while drinking its waters would be gratified.
The largest tumulus, which is nearly circular, is about 60 feet in diameter and 5 feet high at the highest part. In the centre it is only 2 feet 6 inches. The site of this tumulus is marked upon the ordnance map and it is locally known as the "Punch Bowl" or "Devil's Punch Bowl," a designation which, as is well known, has been often applied to barrows, and originated doubtless in the legends and superstitions which found favour with the country people in former days; the bowl or cup-like form being due either to the pernicious habit of explorers, when excavating tumuli, of excavating a shaft or pit in the very centre of the mound, with the expectation of dropping at once on the anticipated treasure, perhaps finding nothing and abandoning the work, or from the fact of the barrow having been raised over cists containing urns or interments by inhumation, which gradually perishing and giving way, led to a subsidence of the soil in the crown of the tumulus.
There is a tradition current among the labourers on the estate that in this hollow portion of the "Bowl" a large stone formerly existed, and it was removed from its position by mischievous people, and sent rolling down the hill, and that, for some time after, it was to be seen near to a ditch or path adjoining Nunwell House. We instituted a careful search with one of the labourers, but was unable to trace the stone. It is possible that it had some association with the tumulus, and perhaps some significance as a limitary mark, or it may have been only placed there in recent times for the support of a staff or pole, the situation of the mound being one which might even be selected for a beacon.
A Bronze Age bowl barrow on Gallows Hill, Arreton Down. The barrow was originally part of a barrow group of three barrows, but is now the only one surviving as an earthwork (For details of the other two barrows see HOB UID 461309 - NMR SZ 58 NW 24 and HOB UID 1458695 NMR SZ 58 NW 105). It measures 24 metres east-west by 19 metres north-south and has a maximum high of 3 metres. Excavations in 1990 located the barrow ditch which was 0.5 metres deep. The mound is truncated on the northeast side by the road. A Highway Commission barrier was constructed in 1815 abutting the barrow. This served as a road block and is visible as a mound about 4 metres wide and 0.5 metres high, at the base of the barrow on the southwest side. The barrow was excavated in 1815 by Thomas Cooke and found to contain seven extended inhumation. All were orientated with the heads to the west. Grave goods associated with the inhumations included knives, buckles, a comb, and a spearhead were also found. The grave goods suggest an Early or Middle Saxon date for the burials. The stone socket of the gibbet, erected in 1730, for Michael Morey, who killed his grandson was found at the centre of the mound. The barrow was re-excavated in 1956 and human remains, probably of these excavated in 1815 were found.

A barrow surviving as an earthwork 20 paces in diameter and 6.5 feet high. (2)
The barrow was excavated in 1815 by Thomas Cooke. In the barrow seven extended skeletons were found including those of a child of about 9 years old and another of about 2 years old. All were orientated with the heads roughly to the west. Near each skeleton, generally under the back, was an iron knife blade. Two circular brass buckles, a bone comb, and a spearhead were also found. The human remains were reburied near the centre. The stone socket of the gibbett, erected 1730, for Michael Morey, who killed his grandson was found at the centre. (3)
The 1815 excavations are the earliest known discovery of Anglo-Saxon or Jutish antiquities in the Isle of Wight. (4)

Brighstone Down encompasses quite a large area and also includes Gallibury Hump which sits just outside the forested area. The Tennyson Trail passes through the middle of it and it's quite accessible by foot from Brighstone village to the South or from the road connecting Brighstone and Calbourne. This area of Downland forms the spine of the Island running east to west and is quite rich in tumuli of varying sizes and states of decay. Of the barrows in the woodland we really only encountered about three and it was quite a surprise to find quite large barrows hidden in the depths of the forest. These were situated just off a track which runs up from the reservoir (bounded by the Tennyson and Worsley Trails) on the southern edge of the forest. The map indicates three barrows near the bend and I was anticipating Bell barrows. As far as I could tell there were only two quite handsome barrows at this position about 2m high and 5-6m wide, but strangely there was a large but quite faint circle comprising a shallow ditch surrounded by a small bank about 7-9m in diameter. This either had to be a small enclosure (there are others not far away) or a reasonably large disc barrow! This was quite difficult to make out properly due to the density of the undergrowth and poor light on an overcast day, but if it does turn out to be a disc barrow then it's possibly the only one on the island as far as I can tell. Having researched I can find no mention of this anywhere else. If anyone has any more information I'd be glad to hear it.
