The Independent Inquiry into Child Sexual Abuse says it has now heard evidence from more than a 1,000 victims and survivors from London.
The inquiry was set up to investigate claims against individuals and institutions.
The milestone comes as new statistics show more than three quarters of survivors believe they are stereotyped as a result of speaking out.
Anthony Baxter has been speaking to Michael May who heads up the Truth Project in London, the part of the inquiry which gives victims a chance to share their experience, and Ruby, one of those who has used the Project.
