Current conservation issues
In view of the serious degradation of this property inscribed on the World Heritage List in 1978, Poland, which anticipates restoration work over a period of thirty years, requested on 31 March 1988 that the Wieliczka Salt Mine be inscribed on the World Heritage List in Danger. Such a request had already been submitted by Poland in 1984, but at its eighth session, the Committee considered that there was insufficient geological information to evaluate the dangers facing this property.
At its twelfth session, the Bureau expressed the wish that an in-depth study of the situation be carried out so as to enable the Committee to take a decision. Despite the repeated efforts of the Permanent Delegate of Poland to Unesco, and due to the complex situation, the required information was not available.
Link to the decision
24. Since ICOMOS was not yet in a position to provide accurate evaluation of the threats to the integrity of the following 2 properties, the Bureau recommended that the Committee's decision on the 2 requests be taken after further study has been carried out:
1. Urgent measures for strengthening the foundations of the wall and to study methods of reconstructing doors, windows and other wooden elements at Bahla Fort (Oman).
2. Equipment and technical assistance needed for restoration work at Wieliczka Salt Mine (Poland).

In the absence of information on the state of conservation of this property and the most urgent needs in terms of protection thereof, the Committee requested that a mission be organized to seek such information before the next session of the Bureau. Therefore, a decision on this matter was deferred.
