Bullwarks mediaevals

Porec surrounded by walls will survive till the 18th century. The ones erected from the 12th to the 16th century mainly follow an antique fortification pattern. Towers preserved till today were built by some head people: the Pentagonal by Nicolo' Lion in 1447, the Round Tower by Francesco Bondulmier in1473, and the Semi-circular by Pietro de Mula in 1475.
