Trani has lost its old city walls and bastions, but the 13th-century fort has been extensively restored as a museum and performance venue and is open to the public.
The castle was commissioned by Frederick II of Swabia in 1230. It was completed three years later, although consolidation of the structure continued for a further fifteen years. Like many other castles, it was modified in the 16th century when Charles V reinforced the defensive structure by adding two bastions equipped with fire arms.
The Castle, with its quadrangular base, is one of the finest existing examples of Swabian defensive architecture. Originally featuring square-base towers on each corner and a central courtyard, it was later fortified with the addition of an external wall. It stands by the sea and was, in the past, directly linked to the water. It used to have a wooden drawbridge.
References:Saint-Georges de Boscherville Abbey is a former Benedictine abbey. It was founded in about 1113 by Guillaume de Tancarville on the site of an earlier establishment of secular canons and settled by monks from the Abbey of Saint-Evroul. The abbey church made of Caumont stone was erected from 1113 to 1140. The Norman builders aimed to have very well-lit naves and they did this by means of tall, large windows, initially made possible by a wooden ceiling, which prevented uplift, although this was replaced by a Gothic vault in the 13th century. The chapter room was built after the abbey church and dates from the last quarter of the 12th century.
The arrival of the Maurist monks in 1659, after the disasters of the Wars of Religion, helped to get the abbey back on a firmer spiritual, architectural and economic footing. They erected a large monastic building one wing of which fitted tightly around the chapter house (which was otherwise left as it was).
