Ventilators, conical stone towers about 20 feet high, were placed about a mile apart along the Aqueduct “to give free circulation of air through the Aqueduct,” in the words of the chief engineer John Jervis. The aqueduct has 21 of these ventilators – this is number 18. Although interesting after a while they all tend to look very much the same… but not this one.

On my walks I’ve passed many of these ventilators, but this one is unique in my experience. Someone (or some people) have placed brightly colored stones around the base. This seems to have happened during the pandemic, possibly to cheer passers-by up. Very nice.
