In 1473, New Lödöse was granted substantial privileges. The Old Älvsborg Fortress was built in the 14th century, located at the Klippan area near what is now the harbour entrance of Gothenburg. After the Danes easily conquered the fortress several times, fortification works was gradually expanded. New Lödöse was burned down by Danish forces in 1521, and after it was initially rebuilt at the same spot in 1526, it was later relocated ("Gothenburg 3") near the Älvsborg fortress, west of the modern town.
