Today’s Friday Photo depicts two surviving mediaeval structures from Rynek Glowny, the main market square of the city of Krakow. Established in the same charter which determined the plan of the city in 1257, the square served as the centre of not only commercial activity, but also civic identity. This can be seen in the tower to the left, all that remains of the town hall, first built in the 13th century, that dominated the square. Just alongside is the Sukiennice, or Cloth Hall. During the later Middle Ages, Europe’s cities experienced rapid growth, which in turn fostered new social hierarchies and relationships. In towns, civic institutions were created, both to regulate and promote the goods produced by the artisan guilds. This relationship between economics and urban governance points to the role of trade in fuelling the creation of cities through charters, and is perfectly expressed in the proximity of these two buildings. Today, however, they survive in slightly altered form. The Cloth Hall’s interior is still devoted to retail, but its appearance was altered by successive renovations from the Renaissance onward, while the town hall’s tower was restored following WWII and now houses cultural events.
