Podčetrtek Castle is one of the oldest castle architectures in the region and formed part of the defensive line against Hungary (Croatia). Despite its venerable age, dating back at least to the Romanesque period, it is mentioned directly in the sources quite late (1261 as a castrum Lansperch). It stands in an extremely dominant position, above the village of the same name. In its long history, it has changed several owners and caretakers, but the most important influence on the castle's architecture today is the Attems family, an important noble family from Styria, which is credited with a thorough Baroque-style renovation, followed by a radical renovation in 1874.
The castle has gradually deteriorated since the end of World War II, when many of the movable and built elements were destroyed and stolen by "casual collectors" and vandals. In recent decades, the fabric of the building has been in a critical state, threatened with total collapse due to lack of maintenance, roof leaks, crumbling and collapsing walls. Due to the waterlogging, the walls or ceilings in the residential part of the castle have partially collapsed and in some cases completely collapsed. In 2020, the Municipality of Podčetrtek became the sole owner of the castle and immediately organised a meeting with the competent conservators of the ZVKDS, Celje Branch. After a thorough inspection, it was decided that the restoration of the castle would be carried out in several phases. The first, priority phase was to prevent further waterlogging of the building by repairing the roof structure, replacing the roofing and draining the storm water. The municipality took immediate action on this phase. At the same time, the clock tower was completely restored and statically stabilised, and two AB panels were installed in the residential part of the castle, after the restorer had removed the surviving stucco. The stuccoes that have been removed and are still preserved have been deposited with the municipality and will be used for the reconstruction of the stucco vaults in future phases.
After obtaining major funding or co-financing from the Recovery and Resilience Mechanism (RRM), the municipality has now embarked on the second phase of the renovation. The latter consisted of the structural rehabilitation of the entire building, the restoration of the façade envelope, and the replacement of the joinery. This phase also included the renovation of the stables attached to the castle. A lift was installed to provide access for the physically handicapped, leading to a viewing platform. The latter was also documented in the Attems family photo library from the late 1930s. The stable was in a very poor state of construction before the works were carried out, and the investor wished to convert it into a modern tourist, promotional, tasting and exhibition space. The viewing platform has a glass pavilion, part of which houses a lift and a staircase leading to a terrace. The glass pavilion was also built to protect the Gothic biforas, which were uncovered, restored and presented during the works.
In order to improve the drainage of storm water, archaeological research was carried out in the atrium of Podčetrtek Castle, with surprising results. Among other things, archaeological structures were discovered that pre-date the - so far known - earliest phase of the castle's construction.[1]
