Pollnagollum is a recorded cave place at Quay in County Dublin. The name suggests a hollow or tube, fitting a cave that may have given shelter, hidden water or simply marked the edge of known land. Whether people entered it with lanterns or passed it with dogs at their heels, the rock would have answered both with darkness and echo.

Pollnagollum is a karst cave formed through the dissolution of limestone by acidic water over thousands of years. It is associated with the River Dargle and is part of the broader network of caves in the Dublin Basin, though its archaeological or folklore history remains largely undocumented.
