Abstract 
One of the most illustrative example of negative consequences of past restoration interventions we can observe on the unique self-portrait of the baroque painter Giulio Quaglio from Laino near Como, Italy. He painted himself on the 1st of July in 1704 on the right wall in the presbytery of Cathedral of St Nicholas in Ljubljana, Slovenia. The paper is going to present interesting examples, demonstrating the nature of decay on wall and ceiling paintings and the consequences of unskilled and unprofessional restoration decisions and interventions in the past. With the mentioned subject we are going to present one part of the conservation-restoration project, executed in 2002-2006 by Restoration centre in Ljubljana under the Institute for the Protection of Cultural Heritage of Slovenia (IPCHS) as one of the most complex conservation restoration projects in Slovenia.
