I have been living in Dublin for a number of years and while walking in Docklands area would pass by a red, several meters high red steel construction on Sir Rogerson’s Quay – my friends were always asking me what that was and I never knew the answer. Only quite recently I actually realised that the shape of the construction has slightly changed since I last saw it, and now there is a little path under it with some explanatory information.
This is the Diving Bell, a piece of engineering art for building deep water quay walls back in the 19th century – and believe it or not, but it was in use until the late 50s of the 20th century! Workers had to perform under literal pressure – the water pressure, being inside the Bell and build Dublin Docklands.
I do not want to spoil the experience – you should go and learn about the last 140 years of Dublin history by visiting this small sight. I recommend to see it in the evening as you can enjoy lovely city lights all around the Liffey.
