The highest bridge in Ireland for 150 years  

Not many people are aware whilst driving into Enniskerry on the R117 that they passing over the Knocksink Bridge. When it was built in 1859 it was Ireland’s highest bridge and an amazing feat of Victorian engineering. During the Second World War holes were drilled in the bridge in order to blast it with dynamite in case of Nazi invasion. The bridge spans a deep glaciated ravine over the Glencullen River known as Knocksink Woods. These woods contain some of the most diverse animals, plants, and insects in the country and are classified as a Special Area of Conservation. If you look carefully you can find examples of Sessile Oaks, Holly, Hazel, Ash, Beech, and Sycamore trees as well as red squirrels, badgers, rabbits, deers, robins, blackbirds, song thrush, wrens, chaffinches, and even buzzards!
