Old Breacacha Castle on the picturesque Isle of Coll is said to be haunted by the mysterious Glaistig, a malevolent female spirit with a shock of white hair. This ghostly presence was known to help prepare the castle for visitors but had a sinister reputation for mistreating strangers who dared to venture onto the site. Those who ventured out of their rooms at night would often find themselves lost and disoriented, unable to find their way back to bed. The Glaistig's motives were shrouded in mystery, leaving many to wonder if her actions were driven by a desire to protect the castle or to cause harm to those who disturbed its peace.

The Glaistig's legend dates back to the pre-twentieth century, a time when the castle was a hub of activity. According to local lore, this ghostly apparition was a harbinger of doom, striking fear into the hearts of those who crossed her path. While some believe the Glaistig to be a malevolent spirit, others theorize that she may have been a guardian of the castle, tasked with protecting its secrets and inhabitants. Whatever her true nature, one thing is certain - the White Haired Woman of Old Breacacha Castle remains a fascinating and chilling presence, captivating the imagination of paranormal enthusiasts and visitors alike.
