This was part of the broader plantation efforts in Ulster during this period, when English and Scottish settlers were establishing new communities across the northern counties of Ireland. The defensive bawn, a fortified courtyard wall typical of plantation architecture, would have provided protection for both the castle and the emerging settlement during these turbulent times.

Today, visitors to Shercock won’t find any visible traces of Piers’ castle above ground. The site has undergone a remarkable transformation; where the castle once stood, the present Roman Catholic chapel now serves the local community. This layering of history is quite common across Ireland, where religious buildings often occupy sites of former strategic importance, reflecting the changing priorities and power structures over the centuries.

The absence of physical remains doesn’t diminish the site’s historical significance. Archaeological records from Davies’ 1948 survey and the later Archaeological Inventory of County Cavan (1995) confirm the castle’s existence and location, even if time and development have erased its physical presence. The chapel grounds in Shercock thus represent a palimpsest of Irish history, from plantation fortification to contemporary place of worship, embodying centuries of social and religious change in this small Cavan town.
