The Grand Canal is an important aspect of the landscape of South Dublin and provides a unique eco system in an urban area. It flows between Clondalkin and Lucan and through the areas of Clonburris, Kilmahudric, Grange, Kishogue and Cappagh linking togeather the natural and the built environment.
It was originally built for transport of people and cargo but after the railways were built its usage fell into decline. Cargo traffic ended on it in 1959
A bog/ marsh ecosystem has developed around the canal. There are also systems of hedgerows and ditches around which many varieties of flora and fauna have developed as well as encouraging all kinds of wildlife into the area.
