Kells Irish Restaurant & Pub is said to be haunted due to its location in Seattle's first mortuary, the Butterworth Building, which was built in 1903. Paranormal activity reported includes the sounds of breaking glass, handprints appearing on windows, and the inexplicable presence of a young girl in a red dress and an older man named Charlie. Other phenomena include glasses sliding off tables, mirrors shattering, and disembodied whispers. The building was originally built as the Butterworth & Son's mortuary, which was the first purpose-built mortuary in Seattle. The building's history in this macabre era of casket viewings and funeral processions is considered a key reason for its reputation for paranormal activity. A spirit, often described as a young girl with red hair or a scarlet velvet dress, is said to play pranks and interact with patrons. An older man, sometimes seen wearing a hat, named Charlie is also reported to inhabit the pub. Reports of glass breaking, mirrors shattering, handprints on windows, and disembodied whispers are frequently mentioned. Guests and staff have also noted sudden drops in temperature and the inexplicable feeling of being watched. The Kells building was featured on an episode of the paranormal investigation show Ghost Adventures. The pub is considered by many to be the most haunted place in Seattle.
