This three-storey limestone structure, built from carefully coursed blocks with distinctive long and short quoins at its corners, features a round arch that spans the roadway below, though modern alterations have somewhat changed its original appearance. The gate takes its name from a local family who likely lived nearby during the medieval period, serving as both a practical entrance point and a symbol of the town’s former importance as a walled settlement.

Visitors approaching from the northwest will spot a pointed doorway that leads to an internal staircase, illuminated by narrow, flat-lintelled windows that pierce the thick walls. The first floor reveals more elaborate architectural details, including a large pointed window facing west that floods the chamber with light, albeit through modern surrounds that replaced the original stonework. Smaller pointed windows punctuate both the eastern and western walls, creating a defensive structure that could monitor approaches from multiple directions whilst maintaining the building’s security.

Today, the tower stands incomplete; its second floor and roof level have long since vanished, leaving only the lower portions to hint at its former height and grandeur. Despite this loss, Blossom’s Gate remains one of Kilmallock’s most tangible links to its medieval past, when the town was encircled by protective walls and served as an important administrative and commercial centre in County Limerick. The gate continues to function as it has for centuries, with modern traffic passing beneath its ancient arch, making it a rare example of medieval architecture that remains integrated into daily life rather than cordoned off as a museum piece.
