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.
The church of the former Franciscan monastery was built probably between 1515 and 1520. It is located in the UNESCO World Heritage Site of Old Rauma. The church stands by the small stream of Raumanjoki (Rauma river).
The exact age of the Church of the Holy Cross is unknown, but it was built to serve as the monastery church of the Rauma Franciscan Friary. The monastery had been established in the early 15th century and a wooden church was built on this location around the year 1420.
The Church of the Holy Cross served the monastery until 1538, when it was abandoned for a hundred years as the Franciscan friary was disbanded in the Swedish Reformation. The church was re-established as a Lutheran church in 1640, when the nearby Church of the Holy Trinity was destroyed by fire.
The choir of the two-aisle grey granite church features medieval murals and frescoes. The white steeple of the church was built in 1816 and has served as a landmark for seafarers.
