Old Aker Church
Old Aker Church was built as a three-naved Romanesque style basilica and constructed from limestone. It is believed to have been erected by King Olav Kyrre in 1080 as a church for all of Vingulmark, the historic area surrounding Oslo. The grounds of Old Aker Church were originally likely the former site of the regional thing during the pre-Christian period.
Oslo Stock Exchange
The over 180-year-old stock exchange building has been the subject of many long debates about how the building should be managed and designed over the years. Several of Christiania's (the name of Oslo between 1624 and 1925) best known business men fought for years to get approved and funded the construction of a stock exchange in Christiania, the capital of Norway from 1814.
