Watch 'Most Haunted': Bron Y Garth Hospital & Beaumanor Hall - Part 1 - Full Episode

In this 'Most Haunted: Extra' the team investigate two separate properties. Yvette Fielding sends Karl Beattie and Stuart Torevell to the very haunted abandoned Bron Y Garth Hospital in North Wales, while she and camera man Gregg Smith head to Leicestershire and the imposing Beaumanor Hall.

With both properties witnessing such sadness, death and mystery, the team have their work cut out in these eventful investigations, which premiered spread across two intense episodes exclusively on the official 'Most Haunted' YouTube channel. You can watch the first one-hour-and-20-minute part of their investigations below...

Situated on the edge of Charnwood forest in Leicestershire is the beautiful Beaumanor Hall, a building that can trace its history back as far as the Norman Conquest in 1066. Over the years the hall has been owned by several influential and noble families, including Lady Jane Grey's uncle, Lord Leonard Grey.

The building we see today was built between 1842 and 1854 by architect William Railton for the Herrick family, who had owned the estate since 1595. The house remained in their possession for over 90 years until World War II when the estate was requisitioned by the War Office. The house has seen many changes over the years, and many of its past residents refuse to leave. Door slam in the middle of the night, phantoms of the hall's past are seen with stark regularity and voices are heard in otherwise empty rooms.

Yvette and Gregg started out their investigation in the cellar. Yvette said, "these underground tunnels I find fascinating, because of the codebreaking that was involved during WWII," some of which was undertaken in the property.

During their investigation, Yvette tried to encourage the spirits of the building to communicate by knocking, singing wartime songs, and whistling and asking the spirits to copy her.
