No stone, no arch, no fragment of wall survives to mark it out. The farm buildings that now occupy the site give no indication of what came before, and a visitor arriving without prior knowledge would find nothing whatsoever to look at.

The chapel was known as the chapel of Simon-Tallagh, a name that links it to the ancient ecclesiastical territory of Tallaght, and by the fourteenth century it had been attached to St Patrick's Cathedral in Dublin. That connection places it within the wider network of properties and dependent chapels that the cathedral accumulated during the medieval period, when such arrangements were a common feature of church organisation. The historian John D'Alton recorded the association in 1838, drawing on earlier sources, and the detail was noted again by Healy in 1974, by which point there was already nothing left to see at ground level.

Coolmine today is a suburban area to the west of Dublin city, and the site itself sits within what was once the rural hinterland of the capital. There is no access arrangement for the public, no interpretive signage, and no monument to locate. The value of the site, such as it is, lies entirely in the archaeological record rather than in anything visible. For anyone interested in the medieval geography of Dublin, the chapel of Simon-Tallagh is a useful reminder that the landscape was once scattered with minor ecclesiastical buildings whose physical presence has been completely erased, leaving only the documentary trace behind.
