In the period 1981–1984, significant restoration work on the interior of the Black Church took place with the financial help of the Evangelical Church in the Rhineland (Federal Republic of Germany). Due to this work, the Black Church could not be used by its parishioners during this period. On 27 May 1984, the church was re-opened with a festive event and a religious service that marked both the 600th anniversary of the beginning of the construction and the re-inauguration of the Church. The religious service was conducted by Bishop Albert Klein of the Evangelical Church A.C. in Romania. This event represented a significant moment in the history of the Black Church Restoration Ad Hoc Collection due to the fact that it was the occasion for the publication of several articles in the local press popularising the history of the restoration process and its achievements. These articles made use of the documents and photos in the collection preserved within the Black Church archives.
