Chapel of St. Doroteje is located on a hill outside the village of Logorište near Karlovac close to the cemetery. It is assumed to have been built in the first half of the 17th century, but has repeatedly made many changes since then. The altar of St. Mihovila originally had the function of the main altar (with sculpture of St. Dorothee in the niche), however, during the 18th century renovation he was removed to the lateral position along the triumphal arch, while the "new" Baroque altar was placed in the sanctuary. When moving the altar of St. Mihovila had some changes: the lateral canopy ornamental wings were moved to the top of the altar, as well as the sculptures below them, the original polycromium was completely repainted, while the ribbed pillars were covered with a lime-painted lining. During the conservation and restoration research, based on the results obtained, the analysis of the layers, binders and pigments of the HRZ chemical laboratory and the chemical probes and the probing of the removal of repainted layers were reconstructed by its original coloristic appearance. It was an altar belonging to the type of small black gilded altars of the 17th century local folk provenance, which we find in a smaller number of the preserved ones in the Karlovac and Jastrebarsko area. During the restoration of the altar there was made carpentry repair ,carving and reconstruction of missing parts, removal of repainted layers, gilding works and retouch made of tratteggio technique. As the altar had to be restored to the originaly position in the chapel, during its conservation and restoration work its original appearance could only be partially presented in the colouristic appearance, while the compositions retained the 20th century appearance. Works on the altar of St. Mihovila started in the Restoration center in Ludbreg in 2012 with conservation and restoration researches and they continued during 2013/14. In December 2014 alter was returned to the chapel. The works were organized in co-operation with conservators of the Conservation Department in Karlovac and financed by the Ministry of Culture of the Republic of Croatia through the regular activities of RC Ludbreg.
