The Hanseatic League was a commercial and defensive confederation of merchant guilds and their market towns. Growing from a few North German towns in the late 1100s, the league came to dominate Baltic maritime trade for three centuries. The golden age left many beautiful buildings to the Northern Germany, most of them representing Brick Gothic style.
One of the most picturesque places in Rostock is the Neuer Markt (New Market Square), with the Town Hall - that was originally built in the 13th century in Brick Gothic style, but extensively transformed in the 18th century, with the addition of a Baroque façade and a banqueting hall. The square also preserved six original, carefully restored gable houses from the 15th and 16th centuries. The other historical houses in Hanseatic style that once bordered the square were destroyed in an Allied air-raid in 1942, and rebuilt in a simplified manner.
Ogrodzieniec Castle is a ruined medieval castle originally built in the 14th–15th century by the W³odkowie Sulimczycy family. Established in the early 12th century, during the reign of Boles³aw III Wrymouth, the first stronghold was razed by the Tatars in 1241. In the mid-14th century a new gothic castle was built here to accommodate the Sulimczycy family. Surrounded by three high rocks, the castle was well integrated into the area. The defensive walls were built to close the circuit formed by the rocks, and a narrow opening between two of the rocks served as an entrance.
In 1470 the castle and lands were bought by the wealthy Cracovian townsmen, Ibram and Piotr Salomon. Then, Ogrodzieniec became the property of Jan Feliks Rzeszowski, the rector of Przemy¶l and the canon of Cracow. The owners of the castle about that time were also Jan and Andrzej Rzeszowskis, and later Pilecki and Che³miñski families. In 1523 the castle was bought by Jan Boner.
