Based on the results of architectural and historical research and restoration research of part of the ground floor of the northern wing of the manor house in Modrý Kameň, we can state that despite the loss of the original materials and alterations, the building has basically preserved its original quality and appearance from the first half of the 18th century. Later modified by creation of newer openings and partitions, probably from the mid-19th century and functional adaptation of the premises at the beginning of the 20th century. The next complete modification of the interiors took place after the mid-20th century. The impaired condition of the stone elements was caused by the surface degradation of the stone. The mechanical interventions in the stone parts were probably the result of the Baroque modification in the 30s of the 18th century and the last general modification from the 1920s.
The basic goal of the restoration intervention in addition to the restoration of the premises will be to preserve and, as far as possible, restore the authentic values of the interiors of the northern wing with the restoration of valuable stone elements of windows, portals and blocks of the armoured entrance gate.
The restoration will be aimed at removing the secondary plasters mounted with cement and removing debris, dirt, secondary coatings from the stone elements.
The stone elements will be cleansed from secondary coatings, the damaged local losses will be supplemented and presented in the original material, so that the authenticity of the stonework is preserved to the maximum extent in the overall resulting effect. The current restoration intervention fundamentally addresses the preservation and stabilisation of their visual and artistic values. During the cleaning work on the façades, fragments of lost details of the façade segmentation were captured, mainly from the courtyard part. The confirmed profile of the horizontal cornice complemented the arcade openings, which were centrally represented by the entrance risalit. From the exterior side, the entrance portal was modified during the early 20th century façade remodelling, with a probable modification of the undergate and the bridge structure levelling by an increase of approximately 30 cm. The armouring of the portal itself is made up of two types of stone blocks, which are precisely placed alternately. This finding also assumes presentation of the stone mass in its natural colour, distinguished from the area of the façades.
