Theories differ as to whether this was originally one large cliff fort comprising a wide promontory, two separate forts now split into three, or whether there were always three separate promontories each with its own ramparts.
Either way, there are three now, separated by Wine Cove and Pepper Cove.
From Cornwall & Scilly HER:
Winecove Point is a complex site of uncertain development consisting of three promontories each with ramparts of various construction. It is assumed to have originated as one cliff castle, subsequently in part eroded away, but it may have developed as one organisation based on the three promontories. Each part of the site is described below; there has been very little work done on this site and the only finds known are a hearth exposed in a cliff face, and at least one spindle whorl has been found here. Such finds indicate that the site was occupied, but the extent of internal activity remains quite unknown. More work is needed on this site. The site is included in the Schedule.
The northernmost promontory of the cliff castle at Winecove Point possibly is a separate cliff castle in its own right. It is defended from the mainland by a single rock-cut ditch 0.3m deep with an inner bank 0.4m high. The rampart is much eroded and silted, as is the rest of the promontory, which is exposed to the worst of the weather. The rampart is continuous but rather lower in the middle, as if for an entrance. There seem to have been no finds in the area, and no evidence for occupation of the site.
The middle of the three promontories that form the Winecove Point cliff castle is better preserved than the others, and is defended by a double ditch with narrow central entrance. A further ditch is said locally to have originated as a track for a steam engine raising marble from a wreck in the cove below. A hearth is visible in the cliff section at SW 8537 7370, on the north-west side of the eroded cliff. A spindle whorl was found in a small cave at SW 8544 7371, on the sheltered south face of the cliff. The whorl is 4.0cm across, and ornamented by incised lines (now in possession of Mrs Taylor at Whitworth). The extent of occupation is not certain. The site is much denuded.
The southern of the three promontories that form the Winecove Point cliff castle is defended by three well spaced ramparts, two of which are rock cut. Only the middle one has an accompanying bank and has a central causeway. The other two have staggered entrances towards the southern ends of the ditches. It is suggested that the inner ditch is not contemporary with the other two on account of its straightness. There are a couple of depressions within what the OS call the sole rampart that may be hut circles. There is no evidence of occupation from finds etc.
