To record the unwritten history of the underground period of the Ukrainian Catholic Church (1946 to 1989) was the first goal of the Institute of Church History of the Ukrainian Catholic University.
Founded in 1992, the institute sent out staff and students to interview people who personally witnessed the life of the underground church.
The institute now has thousands of interviews, historical photos, and documents regarding this period.
Now the institute also conducts research in other eras of the history of the Church in Ukraine.
