The memorial, which celebrates the life of Catherine Eddowes, who was killed by Jack the Ripper, was displayed at the Jubilee Christian Centre on Merridale Street which is near to her former Graiseley Green home.
The 46-year-old, who was born in Wolverhampton, was brutally murdered in London on September 13, 1888, one of at least five victims of the man dubbed The Ripper.
Eddowes, also known as Kate Kelly, spent the last hours of her life sobering up in a police cell.
She was released at 1am and was last seen heading toward the high street. Forty-five minutes later her body was discovered in Mitre Square in Whitechapel. She was killed less than an hour after Elizabeth Stride in what is commonly referred to as 'the double event'.
The plaque was the brainchild of members of the Wolverhampton Civic and Historical Society who have been striving for a plaque in Catherine's honour to be displayed for more than two years. It features an image of Ms Eddowes and reads: "Catherine Eddowes. Born nearby, at 20 Merridale Street, Graiseley Green on 14-4-1842 and murdered on 30-9-1888 in Whitechapel, London. An innocent victim of 'Jack The Ripper'."
The plaque's sponsor, Robin Lumley of Lumley Designs, attended as well as author Russell Edwards, who has written a book about Catherine and the Ripper case called 'Naming Jack The Ripper'.
