The Theatre Royal Portsmouth, is a spectacular location in the heart of Portsmouth, and we are delighted to reopen the Casebook on this remarkable location that we started investigating 20 years ago when we took Most Haunted Live there in 2006. Built on the site of an older theatre, it was remodelled by the famous architect, Frank Matcham. But the theatre has been through a troubled history and the backstage was destroyed by a fire in the 1970s. A glimpse of what they once looked like can be seen in the Ken Russel film "The Boyfriend". Several deaths have been reported in the building and it seems that their spirits may still be there. Who are they… well join us as we re-open the Casebook and see if they return.
Further Information
Join Dark Encounters as we carry out a comprehensive paranormal investigation of the site. You will get to investigate for yourselves; setting up experiments, carrying out the experiments and recording your observations. So whether it is a lone vigil in the haunted dressing rooms, EVP experiments on stage, or Dowsing experiments in the Gods - you will be in the heart of the action. At the beginning of your evening you will have a briefing on ghost hunting techniques and the plan for the evening. Then you will split into smaller groups to carry out the investigation. The teams will be led by experience investigators who will guide you to the correct areas and how to set up the experiments. There will be regular refreshment breaks and then at the end of the evening all teams will have a debriefing as we report the evidence recorded. We will be looking for correlations of phenomena between the groups and previous investigations we have carried out at the location - all recorded in the Casebook of Dark Encounters from the past twenty years.
