Heritage and Climate Changes in Romania: The St. Nicholas Church of Densus, from Degradation to Restoration

The paper present the restoration of Densus Church, Hunedoara County, Romania, initiated more than a decade ago, in view of actual situation and research needs. The investigation with infrared (I-R) thermography was associated with measurements of air temperature and relative humidity. The high humidity inside the church was the main risk factor for degradation of frescoes, since moisture was coming from capillary rise of water. The natural ventilation was improved after restoration, while the insertion of a floor heating and the perimeter drainage in building and surrounding area prevented humidity increase.
