    Poolbeg Lighthouse, Dublin Port, Eire - August 28, 2013

    Poolbeg Lighthouse viewed from Fred Olsen Lines' MS BOUDICCA when departing the Port of Dublin on a cruise from Liverpool via Cóbh. Poolbeg Lighthouse is an active aid to navigation at the mouth of the River Liffey, near Poolbeg, Dublin. 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. Poolbeg Lighthouse, one of a formation of three, is located on the Great South Wall (South Bull Wall), at the Port of Dublin, which extends from Ringsend's Poolbeg peninsula nearly four miles out into Dublin Bay. The wall was the world's longest at the time of its building, and remains one of the longest sea-walls in Europe. One of the other two lighthouses is located on the Bull Wall opposite, and the other on a platform mid-channel. The Poolbeg Lighthouse is a handsome and conspicuous feature in the bay, in which it occupies an almost central position. It is nearly equidistant from Dublin, Dún Laoghaire, and Howth, and commands extensive views of the shores of the bay. The lighthouse when originally constructed, presented an entirely different appearance from what it does today. It was not as high as the existing structure, it sloped much more rapidly towards the top, and was surmounted by an octagonal lantern with eight heavy glass windows. A stone staircase with an iron balustrade led to the second storey, where an iron gallery surrounded the whole building. The alteration to the present form was made in the early part of the nineteenth century. The lighthouse, automated for many years, is managed by Dublin Port Company, whereas most lighthouses in Ireland are managed by the Commissioners of Irish Lights, today part of a larger cross-border body. Historically, the Ordnance Survey Ireland used the low water mark of the spring tide on 8 April 1837 at the Poolbeg Lighthouse as a standard height for all its maps, a practice which continued up until 1958. The Poolbeg Lighthouse is painted red. The green lighthouse on the opposite side of the channel is the North Bull lighthouse, a couple of yards off the end of the North Bull Wall, and another green lighthouse the North Bank Lighthouse is also located next to the shipping channel into Dublin. As with all navigational aids marking a channel, the port side as one heads upstream is indicated by red markers whilst the right-hand side or starboard of the channel is green.

  • North Bank Lighthouse, Dublin Port, Eire - August 28, 2013

    North Bank Lighthouse, Dublin Port, Eire - August 28, 2013

    North Bank Lighthouse viewed from Fred Olsen Lines' MS BOUDICCA when departing the Port of Dublin on a cruise from Liverpool via Cóbh. The North Bank or Northbank 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. Built in 1882, it also affectionately called The Tea Caddy due to its architecture and has also been described as "resembling a giant mailbox on stilts". Completed in 1882, the green lighthouse consists of a square tower with a lantern room and gallery, which is supported by a series of concrete columns. This gives an overall height of 11 metres (36 ft). It is located midway between the end of the North Bull Wall, and Alexandra Quay and the main port. The other lighthouses for the port are Poolbeg at the end of the Great South Wall, North Bull at the end of the North Bull Wall, and North Wall Quay Lighthouse at the entrance to the Alexandra Basin. These lights and the various buoys at the side of the channel follow the convention of green on the right (starboard) and red on the left (port) when entering the dredged channel. The 1923 edition of the British Pilot shows that this has not always been the case, with a partial reversal of colours. Then Poolbeg light was painted black, North Bull had a red tower and North Bank showed an occulting white light from a "tower, painted with red and white bands". Although the fog bell at North Bank is now disused, in 1923 it was still operational, along with other bells at North Bull and North Wall Quay, whereas Poolbeg had a fog siren. Operated by the Dublin Port Company, it is registered under the international Admiralty number A5886 and it has the NGA identifier of 114–6632. With a focal height of 10 metres (33 ft) above sea level, the light can be seen for 16 nautical miles. Its characteristic is an occulting green light, which is lit for seven seconds and eclipsed (or dark) for one second.

    North Bull Lighthouse viewed from Fred Olsen Lines' MS BOUDICCA when entering the Port of Dublin on a cruise from Liverpool via Cóbh. 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. The need for the lighthouse and other improvements to aids to navigation at the port, was described in the proceedings of the Institution of Mechanical Engineers in 1888, following a visit to Dublin by members of the Institute. "The construction of deep-water quays and the improvement of the channel were followed by an increase in the number of passenger steamers entering and leaving the port at fixed hours; and, as this class of traffic developed the need of improved lights and fog-signals was felt." The proceedings also show an early photograph with the four storey tower having a small lantern room at the top of tower, this was later removed, and the light is now being shown from a pole in the same location. North Bull was designed by Bindon Blood Stoney the then Chief Engineer of the Dublin Port and Docks Board, becoming operational in 1880, it originally displayed a white occulting light from a fourth-order Barbier and Fenestre optic. Although the light was fixed, a set of four rotating screens with lenses produced the occulting characteristic of seven seconds lit and eclipsed (or dark) for four seconds. During foggy conditions a fog bell was used, whereby a mechanism struck a 17 long cwt (860 kg) bell "four times in quick succession every thirty seconds". Although the fog bell at North Bull is now disused, in 1923 it was still operational, along with other bells at North Bank and North Wall Quay, whereas Poolbeg had a fog siren. The 15-metre-high (49 ft) wrought iron tower sits on a stonework platform which itself is built upon foundations of "two concrete blocks, each weighing 330 tons". The blocks were cast at Alexandra Basin and moved using a floating sheerleg crane. Operated by the Dublin Port Company, it is registered under the international Admiralty number A5884 and it has the NGA identifier of 114–6628. With a focal height of 15 metres (50 ft) above sea level, the light can be seen for 10 nautical miles. Its characteristic is a green light, which flashes once every four seconds.

The proceedings also show an early photograph with the four storey tower having a small lantern room at the top of tower, this was later removed, and the light is now being shown from a pole in the same location. North Bull was designed by Bindon Blood Stoney the then Chief Engineer of the Dublin Port and Docks Board, becoming operational in 1880, it originally displayed a white occulting light from a fourth-order Barbier and Fenestre optic. Although the light was fixed, a set of four rotating screens with lenses produced the occulting characteristic of seven seconds lit and eclipsed (or dark) for four seconds. During foggy conditions a fog bell was used, whereby a mechanism struck a 17 long cwt (860 kg) bell "four times in quick succession every thirty seconds". Although the fog bell at North Bull is now disused, in 1923 it was still operational, along with other bells at North Bank and North Wall Quay, whereas Poolbeg had a fog siren. The 15-metre-high (49 ft) wrought iron tower sits on a stonework platform which itself is built upon foundations of "two concrete blocks, each weighing 330 tons". The blocks were cast at Alexandra Basin and moved using a floating sheerleg crane. Operated by the Dublin Port Company, it is registered under the international Admiralty number A5884 and it has the NGA identifier of 114–6628. With a focal height of 15 metres (50 ft) above sea level, the light can be seen for 10 nautical miles. Its characteristic is a green light, which flashes once every four seconds.

    North Bull Lighthouse, Dublin Port, Eire - October 28, 2005

    North Bull Lighthouse seen undergoing maintenance in October 2005. 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. The need for the lighthouse and other improvements to aids to navigation at the port, was described in the proceedings of the Institution of Mechanical Engineers in 1888, following a visit to Dublin by members of the Institute. "The construction of deep-water quays and the improvement of the channel were followed by an increase in the number of passenger steamers entering and leaving the port at fixed hours; and, as this class of traffic developed the need of improved lights and fog-signals was felt."
