About the reserve
Kiltonga's ponds look natural and are not. This was marshy ground, and the water bodies were dug in the late nineteenth century by a local linen factory owner — mills needed water, reliably and in quantity, and the low ground here was the obvious place to hold it. Half the ponds and dams in County Down owe their existence to the same industry.
When the linen went, the water stayed, and the site went through a much less romantic phase: for part of the twentieth century it was used as sewage treatment works. That is not the sort of history a nature reserve usually advertises, but it matters, because it explains what happened next.
In the early 2000s the site was turned around — local conservation groups and public bodies working together to reclaim the ground as habitat and open it to the public. The walkways went in, the observation area went up, and about a kilometre of path was built to a standard that a wheelchair could use. In July 2000 Kiltonga became the first site in the UK to be given BT Millennium Miles status for accessible paths.
So what you are walking round is a industrial water supply, then a sewage works, then a nature reserve — and now a place where a family can park for nothing, walk a level kilometre, and watch a swan bring six cygnets out of the reeds. That is a good ending for a piece of ground.
