What is recorded here

Enclosure in Fosterstown South is a double-ditched ring, its inner circle thirty metres across and its outer ditch fifty, buried beneath farmland in County Dublin. It appeared first as a faint shadow in a crop field, then under geophysical instruments and test trenches ahead of the Metro North works. No potsherd or bone emerged to name its keeper, yet the shape itself speaks: someone dug twice, marked a boundary within a boundary, and left a room empty enough for imagination to move through.

A circular enclosure visible as a crop mark on an aerial photograph together with other features that suggest an associated field system (DU011-117----) (SMR file; pers. comm. T. Condit). A further enclosure can be seen to the south (DU011-118----). This site was subject to geophysical survey (08R117) and test excavation (09E 0466) as part of the proposed Metro North development. A double ditched or bivallate enclosure with an associated field system situated to the south was identified. The bivallate enclosure consists of an inner enclosure (30m diam.) which is partially encompassed on the eastern, northeastern and northern sides by a second elliptical enclosing ditch (50m diam.). While no diagnostic material was recovered the morphology suggests a bivallate ringfort (Hession 2009, 23). Compiled by: David O’Connor Updated by: Christine Baker Date of upload: 09 January 2015
