The "Castelletto", situated in a panoramic area, faces Grignano on one side and on the other a parterre surrounded by trees and on a clearing in front of greenhouses at the centre of which there is a fountain. Modelled on eclectic forms on a square base with a terrace facing the castle, the tower and the arbour entrance, the Castelletto has a small number of simply furnished rooms. On the ground floor there is a decoration on plaster painted to resemble wood. On the first floor, on the other hand there is a decoration very similar to the one in "Villa Lazarovich" which can be connected to Maximilian’s decision to transfer to the "Castelletto" his own part of the ornaments of the Villa which was his first residence in Trieste. In fact, the rooms in Turkish and German styles and the room decorated with panels of female figures present strong parallels between the two buildings and highlight the artistic tendencies of the time: numerous decorations, walls covered in paintings, many ornaments, heavy curtains and rooms crowded with furniture.
