Dublin's twenty bridges cross the tidal section of the River Liffey flowing through its centre; they were built over a span of a thousand years. Each has made a contribution to the city's development over time, so much so that it is possible to piece together its history by tracing their construction in chronological order. Starting with Church Street Bridge, Dublin's first, which dates back to the Vikings, and ending with the Rosie Hackett Bridge, erected in 2014, Fergal Tobin charts the rise of Ireland's capital city as never before and reveals how it has been truly made by its bridges.
