Maglaj Fortress is a large castle mentioned for the first time on in 1408 in the charter of the Hungarian king Sigismund. Although it was made in 14th century to serve in the defence of the Bosnian kingdom, not until the time of the Ottoman rule did the Fortress get its final shape. Fortress Gradina was declared a national monument of Bosnia and Herzegovina in 2005.
The Fortress Gradina consists of 5 towers: Širbegova or Kapi tower, Dizdareva or Southern tower, Defender tower, The Captain's or North tower and the Clock Tower. The exact data that we posses about the construction of the Maglaj Fortress is only about the Clock tower, and all the information on the appearance, construction and dimensions of the other parts of the Fortress are currently unavailable.
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).
