City walls of Motovun, Motovun

The medieval walls of the city of Motovun are ring-shaped and semi-ring-shaped and form a concentric plan typical of a medieval city. The oldest core of the city is surrounded by defensive walls from the 13th and 14th centuries, which rest on older foundations, their height is 9 to 15 m, and their length is about 45 m. On the inside, these walls are reinforced with a series of niches that served as loopholes , and on prominent parts they have quadrangular defensive towers. At the top of the walls, today there is a Vladimir Nazor promenade that leads around the highest part of the city, and once this walk was strengthened on the outside with parapets that were removed in the 16th and 17th centuries. A suburb developed on the southern slope of the hill and later on its eastern part a suburb which was also surrounded by ramparts. Over time, these ramparts lost their defensive function and were partly incorporated into built structures. Today they are preserved in traces. All three parts of the city are connected by a system of external and internal fortifications with walls, towers and city gates, built between the 15th and 17th centuries.

The demanding rehabilitation of the part of the walls on the outside of the city and the rehabilitation of the retaining wall of the Barbican included the injection of wells with an injection mixture based on lime and white cement, the dismantling of loose blocks and their partial replacement with new blocks that correspond to the old ones in terms of material, dimensions and processing.
