Poolbeg – Dublin’s Twin Towers

Great South Wall and Dublin Bay

Great South Wall and Dublin Bay

One thing leads to another, and the construction of the Great South Wall in the middle of the 18th century led to the erection of the Twin Towers at Poolbeg.

Ships arriving in Dublin Bay encountered a number of dangers; namely, a shallow estuary which was not only heavily tidal but also very exposed. It did not offer much safety, and many ships and crew were lost in sight of land. By the mid-1750s it was decided to construct a wall to stop the build-up of damaging sandbanks, and to dredge the south side of the river.

Construction began around 1760 with the large one-ton stones being quarried in Dalkey and then ferried to the site.  The distinctive, red Poolbeg Lighthouse was added in 1820.

During the wall’s  construction a storehouse for materials was built, and caretaker’s dwelling beside it. John Pidgeon, the caretaker, began to provide food, drinks and a bed for travellers, and soon the place became known as the Pigeon House. (It has nothing to do with the feathered kind!)

A military barracks was built close by after the 1798 Rising, and it stayed in use until 1897 when Dublin Corporation bought it as the site of the city’s first power station. Over the years the site has been developed, and in 1971 the first of the towers was constructed, followed in 1973 by its almost identical twin, which at 681’ 9” (207.8m) is one foot taller.

Although not much appreciated at that time the chimneys have become, possibly, Dublin’s most iconic landmarks and can be seen from almost any part of the city. They appear on T-shirts, TV shows, movies, videos, are painted by artists, have been celebrated in verse, photographed from all angles and, of course, a friendly sign to travelers arriving and leaving. They were decommissioned by the ESB in 2010. Recently, there have been proposals to demolish them, something which many people vehemently oppose. They are our Twin Towers and I, like lots of Dubliners, hope that they survive. SOS – Save Our Stacks!
