About
The North Bull Lighthouse, is an active aid to navigation located at the mouth of the River Liffey, near Dublin, Ireland. It is one of four lighthouses that help guide shipping into the Liffey, and the Port of Dublin, all of which are operated and maintained by the Dublin Port Company.
Completed in 1880, it was designed by Bindon Blood Stoney an Irish engineer, who also oversaw the construction of the North Bull Wall. The green lighthouse marks the outer end of the wall, which becomes submerged at high tide. On the opposite side of the channel, at the end of the Great South Wall is the red Poolbeg Lighthouse.
