New finds in the City Museum's Treasury

Defense structures and Capuchin monastery
During the Middle Ages and the Early Modern period, the area of Congress Square, as in Roman times, lay outside the walled city. The section of the city on the left bank of the Ljubljanica River, called Novi trg (New Square), began right at the southern edge of the area under archaeological research. Archaeologists excavated the outer margins of the Early Modern period defense ditch, which together with the city walls protected this part of the city. The entrance to the city was possible  by means of a bridge running through the Vicedom (Viceroy) Gate.

A Capuchin monastery was built in the area of the present-day Zvezda Park at the beginning of the 17th century. It featured gardens, work buildings and the corresponding Church of St. John the Evangelist. The French converted the church and monastery buildings into a military store and stables during the Napoleonic conquests (1809-1813), and in 1817 the monastery was finally demolished.
