History:
In 1665 Charles II granted Sir Robert Reading letters patent to
build six lighthouses around the coast of Ireland. A cottage-type
lighthouse (a type of lighthouse unique in Ireland) was established
on Howth Head about 1667. It consisted of a small cottage with
battered walls, which is still in situ, with a coal-burning beacon
on top of a square tower positioned against the eastern gable end
of the cottage. Coal and other requisites were brought to the
lighthouse by horses, carts, and carriages from the quay specially
built for the lighthouse at the village of Howth.
In 1790 Thomas Rogers, Lighthouse Contractor and Inspector to the
Revenue Commissioners, replaced the coal burning light with a tower
surmounted by a lantern. The light source was six Argand oil lamps,
each with a silvered copper parabolic reflector directing the light
through six bulls eye panes set in the lantern, which acted as
crude lenses.
The light, like a number of its contemporaries, was quite often
obscured by mist or cloud due to its position high on the hill, so
the Corporation for Preserving and Improving the Port of Dublin,
who had taken over the fourteen coastal lighthouses from the
Revenue Commissioners in 1810, recommended on 5th December 1811
that the light be repositioned lower down on the headland at the
Little Baily, or Duncriffan.
BAILY LIGHTHOUSE
The new tower and Keepers' dwelling were designed by George Halpin
Senior, the Board's Inspector of Works, who also supervised the
construction which was carried out by the Board's tradesmen. The
fixed white catoptric light comprising twenty four Argand oil lamps
and reflectors was established, 134 feet (41m) above high water, on
17th March 1814. The cut granite tower was painted white and
remained so until 1910 when, on the recommendation of the Engineer
to the Commissioners of Irish Lights, it was changed to its natural
granite colour.
Over the years a number of vessels have run up against the rocks or
cliffs around Howth Head. One such occurrence was on the 3rd August
1846, when the City of Dublin Steam Packet Company's paddle steamer
Prince struck the cliffs in thick fog near the nose of Howth 2.5 km
north of the Baily. The Board could not be sure if fog bells would
have prevented the accident, but agreed it would be advisable to
erect bells sounded by machinery at the station.
With regard to the fog bell that should have been erected in 1846,
George Halpin reported that the erection of the bell at the Baily
had been postponed due to the urgency of other works being
undertaken around the coast. Two months after the tragedy of the
Queen Victoria on 15th February 1853, the Corporation informed the
Board of Trade that the fog bell was in the course of erection.
Although no record survives, the bell would have been in operation
by the end of April 1853.
A Committee was set up in April 1863 to look into better marking of
the south-east coast between Kish and Tuskar. One of its
recommendations was to convert the light at the Baily from
catoptric to First Order dioptric. Messrs. Edmundson & Co. of
Dublin supplied the first order lantern, Messrs. Wilkins of London
the first order dioptric apparatus, and Mr Toomey of Dublin
supplied the cast iron lantern floor, all of which were installed
during the summer of 1865.
Around this time, Mr John R. Wigham of Messrs Edmundson and Company
had patented his inventions for illuminating lighthouses with gas.
Later in 1865 the Board directed Mr Wigham to commence experiments
at the Baily. The gas was at first made from oil, then shale, and
finally rich cannel coal, in a gas works at the station. In the
wake of its success, nine other lighthouses were converted to
either oil gas or coal gas.
The Commissioners of Irish Lights became interested in an air
trumpet foghorn which had been developed by an American, Mr C. L.
Daboll. It was on show at an exhibition in Paris in May 1867 and
was basically a small coal fired hot air engine, which compressed
air in a cylinder on top of which was a reed horn. When the
exhibition closed in November 1867, the fog signal was transported
to Dublin, but was not established at the Baily until 1871. The
horn was replaced by a siren in 1879, and the siren by a G type
diaphone in 1926. It is interesting to note that the bell was not
removed until 1890. Obviously it was used as a standby for Daboll's
horn and in the first few years of the siren.
During 1897 Mr W. Douglass, the Commissioners' Engineer,
recommended that the Baily light should be improved and converted
to flashing. The new light, with a character of one flash every
thirty seconds, came into operation on 1st January 1902. After over
forty years of operation by gas light, the light source at Baily
Lighthouse was converted to incandescent vaporised paraffin when a
Chance Brothers triple 50mm burner was commissioned on 25th October
1908.
Baily's optic was to receive yet another change in June 1972. A
completely new AGA 375mm lens driven by an AGA PRB20 gearless
pedestal was installed. The light source was a 1500W 100V L24
electric lamp. The light was permanently exhibited at Fl W every 20
seconds with a range of 26 nautical miles. The 1902 optic,
pedestal, and rotation machine are preserved in the Maritime
Institute of Ireland's Museum at Dun Laoghaire.
Two semi-detached dwellings for Assistant Keepers were built on the
hill to the north of the lighthouse in 1892, and a detached two
story house was built in 1953 for the Principal Keeper in the yard
below the Lighthouse. New quarters for Supernumerary Assistant
Keepers were constructed in 1973 below the lighthouse on the
opposite side of the yard to the Principal Keeper's dwelling. Baily
Lighthouse was used as a training lighthouse to train Supernumerary
Assistant Lighthouse Keepers before they were transferred to
lighthouses around the coast. The Assistant Keepers' houses were
sold in September 1995.
From 1978 the light at Baily was exhibited in poor visibility when
the fog signal was sounding.
Like all rock and mainland stations, Baily became relieving in
1982. Since 1983 it has been the landward base for helicopter
operations to Kish Bank and Rockabill lighthouses.
On 30th January 1992 the radiobeacon at Kish Lighthouse was
discontinued and replaced by a new radiobeacon and radio
direction-finder calibration service at Baily. In more recent times
utilisation of radio direction finders by mariners has been to a
great extent superceded by more modern technology. For this reason
the Commissioners discontinued their Medium Frequency Radiobeacon
service on 1st February 1999.
After a trial period of three months the fog signal was permanently
discontinued from 11th January 1995.
During 1996-7 the lighthouse was converted to automatic operation.
The Lighthouse Keepers were withdrawn from Baily on 24th March 1997
and left the Service on early retirement. Baily was the last Irish
Lighthouse to be unwatched. The character of the light was changed
to Fl W 15 s on the 27th February 1996 in anticipation of the
automation of the station. The Aids to Navigation are controlled
and monitored via a telemetry link from irish Lights Dun Laoghaire.
The station is in the care of an Attendant who lives at the station
in the former Principal Keeper's house. The light is currently a
375mm catadioptric annular lens with electric L24 lamps in a UVLA
lampchanger.
As part of an extensive upgrade of Vessel Traffic Services in
Dublin Port which was put into operation in July 1999, the
Commissioners of Irish Lights provided facilities for Dublin Port
Company to install radar and communication equipment at Baily
Lighthouse.
