The Old Nick Theatre in Gainsborough, West Lindsey, has a rich history dating back to 1860 when it was originally built as a police station and magistrates’ court. The building served this purpose for over a century before being converted into a community theatre in the 1980s. Its past as a place of law enforcement and justice has left an indelible mark on the structure, with many reporting paranormal experiences within its walls.

One of the most frequently encountered spirits is that of a former police officer, often seen patrolling the corridors in full uniform. Visitors and staff have reported hearing the distinct sound of heavy boots echoing through the building, even when no one else is present. In the area that once housed the cells, people have reported feeling sudden drops in temperature and an overwhelming sense of despair.

The ghost of a young woman, believed to be a prisoner from the building’s days as a police station, has been seen in the theatre’s dressing rooms. Witnesses describe her as having long, dark hair and wearing clothing from the early 20th century. She is said to appear briefly before vanishing into thin air.

During performances, actors and audience members alike have reported strange occurrences on stage. Props have been known to move on their own, and some performers have felt an unseen presence tugging at their costumes. The sound of muffled voices and whispers has been heard coming from empty parts of the theatre, often described as sounding like a courtroom in session.
