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.[1] First established in 1767, it initially operated on candlepower[2] but this was changed to oil in 1786.[2] It was re-designed and re-built into its present form in 1820.[3]
