Oxmanstown Green was, by historical accounts, a common of indefinite extent, which is a telling phrase: it suggests a space that existed more through custom and use than through any carefully drawn surveyor's line. Part of it served as a fair green, a designated area where markets and livestock fairs were held, the kind of public ground that formed the social and commercial connective tissue of early modern Irish towns.

The green's story effectively ends in 1665, when it was enclosed. Enclosure, in this context, means the conversion of common land into private or formally managed ground, cutting off the public rights of use that had previously defined it. According to Somerville and Large, writing in 1996, this was the moment Oxmanstown Green ceased to function as the open, communally accessible space it had been. The date places this squarely in the Restoration period, a time of considerable reorganisation and development in Dublin, as the city expanded northward across the river and new streets and estates began to impose a more deliberate order on previously informal landscapes.

Today the area around Oxmanstown falls within the older residential and institutional fabric of Dublin's north inner city, and there is no surviving green to visit in any recognisable form. What remains is the place-name itself, preserved in streets and references, and the faint outline of a civic geography that predates the city's modern street plan. Anyone with an interest in how Dublin's public spaces evolved, or in the quiet erasure of common land that happened across these islands in the seventeenth century, might find it worth walking the district with an old map in hand, comparing what was once open ground against the buildings and roads that replaced it.
