Międyrzecz Castle was built around 1350 by Casimir III the Great in the place of a former gord from the second half of the ninth century, located on a small hill in between two floodplains of the Obra and Paklica Rivers.
Due to the location of the stronghold, the castle was expanded and modernised, although that caste itself did not go through any major battles in the medieval times. In 1474, King Matthias Corvinus of Hungary took over the castle. In 1520, the castle was heavily damaged by the Teutonic Order during the war with Poland, after which the castle was modernised and in 1574 two bastions were built around the castle.
In 1655, the castle was destroyed by the Swedes. In the first half of the eighteenth century the castle was so damaged that even after reconstruction the castle was not able to be used. After the Second Partition of Poland the Prussian forces gave the castle to a Prussian family. The interior of the castle was used as a warehouse and the top floors for a winery.
Since 1945 the castle is used to house a museum. In the years of 1954 to 1958 a number of archaeological excavations were carried out. In the 1950s and 1960s the castle was renovated and stopped the castle from becoming a ruin. The gatehouse and nearby living quarters were reconstructed.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
