Palmanova with its perfect nine-point-star shaped plan, monumental entrance gates and three rings of fortifications is a model of an ideal Renaissance town and UNESCO World Heritage site. Aquileia, an important city in the Roman Empire and later a major centre for the spread of Christianity to northern and north-eastern Europe, was declared a UNESCO Heritage Site due to the vast extension of its archeological area and the artistic value of its early-Christian mosaics. The outstanding Patriarchal Basilica is definitely worth a visit. Grado has a fascinating Venetian-style historic town centre. Wander through the narrow streets and admire the picturesque fishermen’s houses.
