Recently I’ve been spending a lot of my time researching the tunnels underneath Dublin. Between old mines, wells, underground rivers and sewer systems there is supposed to be quite a bit of interest under the city and it’s suburbs. One of the more interesting tunnels I’ve come across so far in my research is “The Clone”, a tunnel containing a diverted river running underground for nearly a mile in length. Compared to the drains in the UK or to some in the city centre of Dublin this drain isn’t hugely interesting but I hope you enjoy the below photos nonetheless. All going well there’s much more to come from underneath Dublin!
