Nicknamed "Sommerbyen" ("Summer City"), Norway's fifth-largest city has 78,000 inhabitants. Norwegians come here for its sun-soaked beaches and beautiful harbor. Kristiansand has also become known internationally for the outdoor Quart Festival, which hosts local and international rock bands every July. According to legend, in 1641 King Christian IV marked the four corners of Kristiansand with his walking stick, and within that framework the grid of wide streets was laid down. The center of town, called the Kvadraturen, still retains the grid, even after numerous fires. In the northeast corner is Posebyen, one of northern Europe's largest collections of low, connected wooden house settlements, and there's a market here every Saturday in summer. Kristiansand's Fisketorvet (fish market) is near the south corner of the town's grid, right on the sea.
