The share of the Furlan builders was very important as regards the building of Ljubljana, especially in the 18th and 19th centuries. Genoa-born Anton (Antonio) Cragnolini (1809—1837) was one of them. He finished his studies of the ornamental sculpture at the Venetian Art Academy and then worked for some years with his father Cristofor who was a master builder in Celovec. At the beginning of the 30’s he set up some important buildings in Ljubljana and in Zagreb, displaying a great skill and susceptibility to stylistic novelty. The intertwinement of unfortunate circumstances tragically stopped his steeply rising life-route. The article deals with Cragnolini’s Ljubljana works and his role in the Slovene architecture of the first half of the 19th century.
