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
Oslo was destroyed several times by fire, and after the fourteenth calamity, in 1624, Christian IV of Denmark and Norway ordered it rebuilt at a new site across the bay, near Akershus Castle and given the name "Christiania". Long before this, Christiania had started to establish its stature as a centre of commerce and culture in Norway. The part of the city built starting in 1624 is now often called "Kvadraturen" because of its orthogonal layout in regular, square blocks. The last Black Death outbreak in Oslo occurred in 1654. In 1814 Christiania once more became a real capital when the union with Denmark was dissolved.
