Beneath and behind it lies the ghost of a second rampart, the outer ring of what was once a double-banked ringfort, almost entirely erased except for that one surviving arc where a later generation found it convenient to borrow the ancient earthwork as a ready-made boundary.

Ringforts, known in Irish as raths, were the most common form of rural settlement in early medieval Ireland, typically enclosing a farmstead within one or more earthen banks and external ditches, called fosses. The example at Peake presents a circular enclosure roughly 36 metres in diameter, defined by an earthen bank standing about 1.2 metres high. A shallow fosse runs along the northwest exterior, and on that same side the bank is stone-faced on its outer surface, suggesting some additional effort was put into reinforcing that particular stretch. The entrance faces south, which is not unusual for ringforts of this type. Writing in 1939, the scholar Hartnett noted that the site had originally been a double-ramparted fort, meaning it once had a second outer bank encircling the inner one. That outer ring has been almost entirely levelled, leaving only the northwest remnant, now absorbed into the field boundary system that parcels up the surrounding pasture.

What makes the Peake ringfort quietly interesting is precisely that palimpsest quality, the way the modern landscape has written over the ancient one while leaving just enough of the original visible to read the earlier version underneath. The stone-facing on the northwest bank, the fosse, the southward-facing entrance, and that borrowed field fence all sit in ordinary grassland, waiting for a careful eye to put them together.
