The Kristiansand Posebyen takes in most of the 14 blocks at the northern end of the town's characteristic kvadraturen (square grid pattern of streets). It's worth taking a slow stroll around this pretty quarter; its name was given by French soldiers who came to reposer here (it's French for 'relax').
A scale model (with buildings around 1m high) of the city as it appeared when designed by Christian IV is on view at Vest-Agder Folk Museum . The annual Kristiansand guide, published by the tourist office, includes a good section called 'A Stroll through Posebyen' to guide your wandering. The most well-preserved buildings include Bentsens Hus , which dates to 1855, the former post office dating to 1695 and Gyldenløves gate 56 (1802).
