About
Poolbeg Lighthouse (Irish: Teach Solais an Phoill Bhig) is an active aid to navigation at the mouth of the River Liffey, near Poolbeg in Dublin, Ireland. First established in 1767, it initially operated on candlepower but this was changed to oil in 1786. It was re-designed and re-built into its present form in 1820.
