Archaeological Research
In the early of the 90s of the 20th century the first archeological research focused on the area of the lower courtyard, i.e. eastern part and dumps near the barbican, was carried out. The research was conducted by PhDr. Václav Hanuliak from the Regional Monuments Board in Banská Bystrica. Its results confirmed settlement (farm buildings) in the lower courtyard and intensive settlement of the castle in the period of 17th -19th centuries.
Archeological research continued in the later 90s and was conducted by Mgr. Peter Mosný from the Regional Monuments Board in Banská Bystrica. He conducted the phase-by-phase research of the part of the upper castle (basement area). The research proved rebuilding carried out in the 15th century as part of the widening of the upper castle area by building of new fortifications. The research brought new information about service facilities (kitchen, storage tank) and structural modifications of renaissance adjacent buildings.
In connection with the change of the owner, since 2002, castle complex restoration activities have been also continued in the research area (historical-architectural, restoration and archeological). On the basis of the results of this research, castle restoration designing work was initiated. In the scope of castle complex renovation, the advance archeological research led by PhDr. Karol Pieta from the Institute of Archaeology of the Slovak Academy of Sciences in Nitra was carried out. The research exposed architecture of the oldest castle from the 13th century- the walls and parts of the preserved roads, which were partially destroyed during construction works at the upper castle in the Middle Ages. The research confirmed written reports on the castle break-down which took place in 1441.
