Oslo
The rock carvings at Ekeberg were created during the stone age, 4,000-5,000 years ago. There are 13 carvings, ten of which portray animals, one that portrays a person, one that depicts something resempling a trap, and one bird-like figure.
Rock carvings have been found at two other places in Oslo; at the University at Blindern (in and next to the chemistry building), and in Niels Juels gate (these can be seen in the Historical Museum).
