Place & story
A lower light beneath the cloud
The first lighthouse on Howth Head, established around 1667, combined a cottage with a coal-burning beacon. A replacement oil light followed in 1790, but its high position left it vulnerable to mist and cloud. George Halpin designed a new tower and keeper’s dwelling lower down at Little Baily. The light began operating there on 17 March 1814, using twenty-four oil lamps and reflectors. Its granite tower was originally painted white; the stone’s natural colour was exposed in 1910. [2]
Testing gas and fog signals
Baily became a testing ground for lighting technology when John R. Wigham began experiments with gas illumination in 1865. Gas was produced at the station, first from oil, then shale and finally cannel coal. The system’s success encouraged its adoption at nine other lighthouses. Sound signals also evolved: an air trumpet installed in 1871 gave way to a siren in 1879 and a diaphone in 1926. These changes addressed the limits of a visual warning during poor visibility. [2]
The old optic across the bay
The large optic that entered service at Baily on 1 January 1902 survives in the National Maritime Museum in Dún Laoghaire. Removed during modernisation in 1972, it retains its lens, pedestal and weight-driven clockwork mechanism. Irish Lights staff helped move and reassemble it at the museum. Its considerable weight required reinforcement beneath its display position. The exhibit preserves the machinery behind the flashes that once swept across Dublin Bay. [3]
The keepers’ departure
On 24 March 1997, Baily’s permanent keepers departed as the station passed to automatic control. Reporting from the occasion, Lorna Siggins described principal keeper Eugene O’Sullivan lowering the Commissioners’ flag shortly before noon. Former colleagues and lifeboat crews attended the changeover. The event marked the end of permanent lighthouse keeping on the Irish coast, giving this particular headland a place in the wider history of maritime work. [4]
