The Villa Decius Association, as a cultural institution with its offices in a historic building, the Villa Decius, systematically updates its rooms while maintaining the character of their stylish character. In 2010 – 2012 special care was taken of the furnishing of the Sala Kominkowa (Fireplace Room) and Alkierz (Alcove) on the ground floor of the building. The rooms were fitted out with a set of 19th century furniture (wardrobes, dresser, dressing table), with especially designed curtain poles to match the character of their barrel vaults. In 2010, a new modern lighting system was installed in the Lubomirski Hall; it was ensured that this does not interfere with the historic fabric of the room. The Association also acquired tapestries, which adorned the ground and first floor rooms and the stairwell walls.
