Did you know that the hypodermic syringe was invented in Dublin? Or that a Dublin man invented perforated stamps? And where in Dublin can you see the ingenious engine that electrified the world? This fascinating guided tour is packed full of surprises. We’ll tell you about great Irish scientists, a new material that could get you inventing, and finish with Alan Turing’s favourite song.

Even Dubliners who think they know the city, are amazed at what they discover on this tour, so do bring a camera.

Our walk starts in the historic grounds of Trinity College Dublin, then we stroll via elegant Kildare Street, passing Leinster House (home to the Irish parliament and senate) and Dawson Street, to end at St Stephen’s Green.
