The main street - Karl Johans Gate stretches from east to west from the East Railway Station to the Royal Palace. It is the most famous shopping street with a lot of street vendors, artists, musicians, actors and, of course, tourists from all over the world.

Almost all the buildings of this street were built in 20-50-ies of the XIX century by the royal architect H.D.F. Linstow, dreamed of turning it into a "Norwegian Champs Elysees." Next to the building is the University of Historical and Ethnographic Museum and the National Gallery, which presents the most important collection of paintings by Norwegian artists, including works by Edvard Munch.

The building of the Royal Palace was built in the first half of the XIX century in the classical style. The palace stands on a small hill in the middle of the park and in front of it is a statue of King Karl Johan XIV. Nearby is another interesting museum - a museum-apartment Ibsen.

ST. Olav attracts visitors with its baroque altar, stained glass windows and unusual painted ceiling and arches. Front of the cathedral on the Market Square is a monument to King Christian IV.
