From the campus you can walk a range of famous sites 10-20 minutes: the Oslo Fjord, the 15th century fortress, the city hall where we will have a reception, the palace, restaurants which will not be cheap and other eating places we can recommend, the concert hall, theatres, art galleries, cinemas, many beautiful parks.
Don't get confused and go to the wrong campus. Ours is called in English Oslo University College but what will be written up might say only Høgskolen i Oslo. There is a tram that stops right beside it (called a trikk) and it's a 10 minute walk to the National Theatre Station (T-barn). The 'other' campus (not where the conference is) is Universitet i Oslo (Oslo University). It's a short tram ride from the city and the University College where we are.
