The Adelphi Theatre, located in London’s West End, has a rich history dating back to 1806 when it was founded as the Sans Pareil. Renamed the Adelphi in 1819, the theater has undergone several renovations and reconstructions over the centuries. The current building, opened in 1930, stands on the same site as its predecessors.

The Adelphi is renowned for its paranormal activity, with numerous ghost sightings reported over the years. The most famous spectral resident is believed to be the spirit of William Terriss, a popular actor who was murdered at the stage door in 1897. Terriss has been seen in various parts of the theater, often dressed in the gray suit he wore when he was killed. Staff and visitors have reported feeling his presence, hearing unexplained footsteps, and witnessing doors opening and closing on their own.

Another ghostly figure associated with the Adelphi is that of a young actress named Mary Bracegirdle. She is said to have died of a broken heart after being jilted by her lover. Her apparition has been spotted in the upper circle, sometimes accompanied by the scent of lavender perfume.

The theater’s dressing rooms are also said to be haunted, with actors reporting strange occurrences such as objects moving independently and sudden temperature drops. Some have claimed to see shadowy figures or feel an unseen presence watching them as they prepare for performances.

In the auditorium, patrons and staff have reported seeing a man in Victorian-era clothing sitting in the stalls, only to vanish when approached. Mysterious laughter and whispers have been heard echoing through the empty theater, adding to its eerie atmosphere.
