I have never been able to decide if there are three distinct lakes or one lake divided into three sections by walls and waterfalls but there are two separate bridges. To the best of my knowledge, the water for the lake(s) is fed from an underground supply and flows downhill [of course] in the same direction as the River Dodder.
The Dodder Valley is the latest section of public land to be developed into a greenway for pedestrians and cyclists and to the best of my knowledge there are three pedestrian bridges. One of the bridges is located in Rathfarnham and crosses the Dodder from Dodder View Road into Bushy Park.
On a previous visit I was told that this is a "folly" but today I realised that is [was] a shell house. It would appear that it was decorated with shells inside rather than outside.
