Fredriksholm Fortress

Fredriksholm Fortress is a ruined stronghold on a small island off Kristiansand's coast, with two main sections: a lower area near the waterline and an upper section crowned by a tower that once held royal chambers. The stone walls and compact layout reflect the military engineering style of the period.

Construction began in 1655 under King Frederick III of Denmark and was completed in 1662, serving as part of Norway's coastal defense network. It represented an investment in fortifying the realm during a period of regional maritime rivalry.

The fortress structure represented Danish-Norwegian military architecture with its strategic positioning and dual-level design incorporating both defensive and residential functions.

The site is accessible only by boat from Kristiansand harbor, with tours operating mainly during the warmer season. Wear sturdy shoes as the grounds contain uneven stone structures and weathered ruins.

In 1910, the fortress temporarily held roughly one hundred Greenland sled dogs destined for Roald Amundsen's South Pole expedition. The animals waited there for health checks before departing on their historic journey.
