Today, the student-teaching church of St. Feоdor Ostrogski is not only a cult building. The collection of iconography kept in the church is part of the NaUOA museum fund and was collected mainly thanks to university graduates. Thus, the temple is one of the exposition sections of the university museum, and its visit is part of the excursion route.
The collection consists of icons of the XVIII-XIX centuries and modern works of the artist Yuri Nikitin. The decoration of the church is an iconostasis created through the cooperation of the Ostroh Academy and the National Academy of Fine Arts and Architecture (NAFAA). NAFAA students under the direction of artist Oles Solovyov make the icons in the style of the Ostroh icon-painting workshop.
The church also exhibits a unique icon Christ Pantocrator and St. Stephen. On it, two chronologically different in the time of writing images overlap strangely. Compositionally it looks as if Stephen covers the mouth of Christ. The tragic and at the same time mystical history of the icon does not leave indifferent any visitor of the museum.
