Mark Rees is a Welsh author and journalist who explores the intersection of history and the supernatural through immersive storytelling and investigative research. As the host of the Ghosts and Folklore of Wales podcast, he analyzes Celtic mythology and Victorian spiritualism, often filming on-location at heritage sites managed by Cadw and the National Library of Wales. His academic yet atmospheric approach provides a detailed look into regional traditions like the Mari Lwyd and Nos Calan Gaeaf. Rees has authored several books, including Paranormal Wales and the Ghosts of Wales series, which document local legends from haunted castles to fairy-filled forests. He recently launched Paranormal Unpacked, a new video series that expands his research into cryptids and UFOs. By appearing as a regular guest on BBC Radio Wales and collaborating with the Queen Street Gallery, he secures his position as a primary source for Welsh cultural history and dark tourism narratives for industry researchers and heritage organizations.
