The excavation, carried out ahead of the carriageway's construction, revealed not one but two circular timber structures and the scattered material evidence of people who had lived, worked, and buried their dead on this stretch of the Wicklow coast thousands of years ago.

Both structures measured around ten metres in diameter and were identified through patterns of post-holes, the circular arrangements of holes left in the ground where upright timber posts once stood, indicating that roundhouses or similar roofed enclosures once occupied the site. The first of these, designated Structure I, was defined by a double ring of post-holes, several of which contained cremation deposits alongside sherds of Bronze Age pottery, suggesting the building carried some ritual or commemorative function alongside any domestic use. Structure II, defined by a single row of post-holes, had its northern edge cut through by later pits and post-holes, which points to continued activity on the site across different periods. To the east, three linear ditches formed what appears to have been a probable enclosure with an entrance facing east. Among the other finds were six saddle querns, the flat grinding stones used to process grain by hand, a fragment of bronze, sherds of Early Neolithic as well as Bronze Age pottery, and hearths. Two kilns were also excavated, and a rotary quern, a more sophisticated grinding device than the saddle type, was recovered from the larger of the two. The combination of grinding equipment, kilns, hearths, and a possible metalled surface suggests a community engaged in food processing and small-scale craft production over an extended period.
