If you happen to walk by, certainly poke your head in and check it out. It appears to be in need of repairs, with the interior just so-so. I hate to give it an average rating, but, even that is generous. A quick in and out is all that is required.

Oslo Cathedral is the 3rd Cathedral in the Norwegian Capital. Formerly Our Savior's Church the Church dates to 1694 and underwent renovation last from 2006 to 2010. Look to bronze doors and a high tower for architectural highlights, while the interior features elegant stained glass and modern paintings.

Oslo Cathedral — formerly Our Savior's Church — is the main church for the Church of Norway Diocese of Oslo, as well as the parish church for downtown Oslo. The present building dates from 1694 to 1697. The Norwegian royal family and the Norwegian Government use the cathedral for public events. In August 2001, Oslo Cathedral was the site of the wedding of Prince Haakon, and Princess Mette-Marit Tjessem Høiby. I attended their Christmas concert. I was fortunate to get one of the last 6 tickets for sale. WINNING! If you plan to go in the future, make a reservation at least 3 weeks in advance. Highlights: Kringkastingsorkesteret (Norweigan Orchestra Radio Orchestra), Oslo Cathedral Boys Choir, Trefoldighet Girls Choir, Oslo Cathedral Youth Choir, Consortium Vocale Oslo, among others.

This is actually quite a small cathedral to visit, and is not overly ornate unlike some other European cathedrals out there. There is however some beautiful ceiling artwork right across the interior as you look up which is worth spending some time marvelling at. Church services are still held here on a regular basis, so you are reminded to act respectfully when entering as well as encouraged to make a donation given its free to enter as well. They do have volunteers on site sometimes to help with general enquires and selling small items from a small cabinet near the entrance like the cathedral guidebook. When I visited there wasn't anyone there besides other tourists so this may be dependant on the time of day that you visit.

Wanted to see this Cathedral -- not so impressive from the outside, but quite lovely inside. Seems to be used as a community space/concert space more than a religious space at this point. Gorgeous pulpit, organ pipes and ceiling. Definitely worth a visit

The Oslo Cathedral is a famous landmark at Stortorvet, the main square in downtown Oslo. I t dates from 1697 and may be small in comparison to more famous cathedrals. However it is actually quite nice inside and has been beautifully restored. Admission is free
