For Scott Montgomery (21) from Carrickfergus, it was the history of the hills that added another dimension to the experience – both human history, as fairs have been held on Cave Hill, and history on a longer time scale.

“It’s interesting from a geological point of view if you think about its formation with the caves,” he says.

“You can actually see on it the layers of where was what and what was covered in ice way back when.”

There is history of another recent sort as well.

Polly has found many prayer cards scattered across the hills during her hikes.

“And people put up a lot of, like, memory plaques and things like that, because I think people get that it’s a beautiful space.

“So it becomes really significant for people.”

That significance is something Scott hopes the photos will help convey.

“I haven’t been outside of the country much, but when I have, it makes you realise that these sort of grand green areas and all our hills and things – they’re few and far between elsewhere.

“We have to appreciate what we have and make sure we defend it.”
