Question: What European capital used to be called Christiania?
Oslo, Norway’s capital and biggest city, has gone through several names in its 1,000-odd years of existence. Its current name is the oldest one, and that’s what inhabitants called the first settlement on the east side of the Bjørvika inlet, which likely appeared around 1000 C.E.
After a catastrophic fire in 1624, King Christian IV declared that the town should be rebuilt in the area below the Akershus Fortress. He changed its name to Christiania, in honor of himself. Beginning in 1877, the name was spelled Kristiania. In 1925 it was changed back to its original moniker, Oslo.
Answer: The correct answer is Oslo
