It does not mark a boundary, carry a sign, or support a structure. It simply stands, partly embedded in the mud, and the most that can honestly be said about it is that it may once have been used for tying fishing nets.

That careful, unassuming description comes from a 2010 intertidal archaeological survey by O'Sullivan and colleagues, who catalogued the material traces of human activity along Ireland's foreshore. The Fergus Estuary, which feeds into the Shannon, would have supported fishing communities for centuries, and staking nets in tidal mudflats was a practical and widespread technique, allowing fishermen to secure gear against the pull of the tide without needing a boat or a pier. Whether this particular stake dates to last century or considerably further back is not recorded. Its timber has not been dated, its species not identified in the available sources. It is simply noted, catalogued, and left to sit in the mud as it has presumably always done.
