The history of Stavanger is inextricably linked to the history of Norway. Although traces of human settlement in this region can be traced back to the end of the Ice Age, the official date of Stavanger's founding is considered to be 1125. This year marked the beginning of the construction of the famous Stavanger Cathedral and the establishment of a bishopric. It was the acquisition of this status as a religious centre that provided the impetus for the transformation of a small settlement into a fully-fledged city and the administrative hub of the region.
Its geographical location on the shores of the North Sea has always played a key role in Stavanger's development. In the Middle Ages, the city became an important trading point on the southwest coast. The city's economy has been closely tied to the sea for centuries: first through the fishing and export of herring, then through shipping and the canning industry, which flourished in the 19th and early 20th centuries. The city's name, derived from the Old Norse words "stafr" (staff) and "angr" (fjord), also reflects its location by the fjord. The early economy was entirely dependent on the sea, making the city one of the key suppliers of fish.
Although its religious role temporarily weakened after the Reformation in 1536, the city received a powerful new impulse for development in the 20th century. In 1969, oil was discovered in the North Sea, transforming Stavanger into the "Oil Capital" of Norway. Despite modern development, the city carefully preserves its past. Cultural life was originally centred around the cathedral, which remains one of the best-preserved medieval cathedrals in Norway today. The architectural appearance of the old town, Gamle Stavanger, with its white wooden houses from the 18th and 19th centuries, still preserves the memory of times when the city lived by the sea and trade.
