The fishmarket in Oslo, which at the time of the photo was named Christiania. (later Kristiania). Probably 1870'ies. On the right lies a big Jakt, which would not be used for fishing, but indeed for fish-carrying. Just outside the market, the sailing fishermen, and further out a couple of square riggers. Around the wharf, small row-boats offering what's been freshly caught out in the fjord. In the right corner a three wheeled perambulator looks to have been left alone, so the mother could study the content of a cart.
