As the sun began to lower towards the horizon we walked around the tower where the outline of farmhouses, thought to date from the Bronze Age, are still clearly visible. These dwellings were circular with central fire places.
We imagined how it would have felt to live there, dark winter nights around the fire, the work they would have done and the tools they used. The boys imagined the children that once lived here, talking about them, giving them names. Rohan asked me if he said hello to them, would they hear?
To walk among these traces of lives, memories in stone, is a wonderful way to take a moment to think of those who were here before.
