The attraction will create a creepy atmosphere including scary music, temperature controls and smells as well as projections and spooky props.
This will also include an escape room themed on the horror story located in the basement, where guests will have to escape the clutches of Victor Frankenstein who has gone mad.
However, there will also be accurate pieces of the time including period costumers, artefacts and some of Mary Shelley’s letters.
Johnathan Willis and Chris Harris, who are behind the attraction, said they decided to create it after thinking that the author wasn’t celebrated enough.
Mr Willis said: “Chris proposed this one day, maybe about a year ago.
“He said ‘did you know that Mary Shelley had written Frankenstein in Bath’, which I didn’t.
“It was one of those ‘that’s going to work, we’ve got to do it’. We’ve got on with it and here we are now.”
Mary lived in Bath as a 19-year-old in 1816, with the novel first published anonymously in 1818 – and it was thought to have been written by her husband at the time.
