What is the X in X-mas?
town and seaport, southern Norway. Located on the Skagerrak (strait between Norway and Denmark) at the mouth of the Otra River, it has a spacious, ice-free harbour, protected by offshore islands, and is the largest community of Sorlandet region. It was founded and fortified in 1641 by King Christian IV of Denmark and Norway, after whom it is named; in 1660 the Christiansholm fortress, now a tourist site, was built. Christian intended the town to be a leading commercial metropolis, but it remained relatively unimportant until the late 19th century. It is now a busy transportation centre and probably the most important town on the Oslo-Stavanger rail line. It provides ocean freight service to numerous European and American ports and a car ferry across the Skagerrak to Hirtshals, Den. Kjevik Airport, northeast of the town, has direct flights to the principal cities of Norway and to Copenhagen. An important industrial centre, Kristiansand has shipyards, textile mills, and metal- and wood-processing plants. Food processing (flour and fish) is also significant.
