A First Nations artist will give a spiritual touch to Banff's historic Cave and Basin National Historic Site of Canada through a mural that came to him in a dream.

Roland Rollinmud was commissioned to paint a mural that depicts his own son, grandson, and nephew and will be displayed at the entrance to the cave.

His artwork is influenced by his Stoney Nakoda First Nation heritage in the Alberta foothills.

Rollinmud says the mural is based on stories his grandparents told him when he was a child.

According to the history of the facility, three railway workers discovered warm water springs at the site in 1883, but First Nations people inhabited the Banff area for thousands of years before that.

Rollinmud says it's a spiritual site that natives visited only 4 times a year.

"In our custom you can receive your strength and everything you need within the walls of that cave," said Rollinmud.

"It's not just about the stories, it's about the energy behind it and the love and the connection and compassion that they all have for the land and mother earth and each other, and everyone on earth. They want to share this story with everybody," said Historian, Jan Gale.

The Cave and Basin is currently undergoing a two year, $14 million renovation and will reopen next summer.

A bronze cast of the three railway workers climbing down a log into the cave will also be part of the exhibit.
