What is recorded here

Siege of Derry Boom Stone is a "the boom stone" (traditionally part of 17th century boom across the river foyle during the siege of derry) in County Derry, Ireland. Perhaps the stone still bites the river bed where the boom crossed, marking the line no invasion could swallow.

The recorded Boom Stone is traditionally linked to the boom placed across the River Foyle during the Siege of Derry.

The Siege of Derry Boom Stone in County Derry is associated with the 1689 siege when Protestant defenders held the city against James II's Catholic forces during the Williamite War in Ireland. The boom across the River Foyle helped prevent James's fleet from reaching the city, playing a key role in the successful defense that became a symbol of resistance in Irish history.
