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.
Architecture of Norway
Architect Carl Frederik Stanley (1769–1805), educated in Copenhagen, spent some years in Norway around the turn of the 19th century. He did minor works for wealthy patrons in and around Oslo, but his major achievement was the renovation of the only seat of higher education in Christiania, the Oslo Katedralskole, completed in 1800. He added a classical portico to the front of an older structure, and a semi-circular auditorium that was sequestered by Parliament in 1814 as a temporary place to assemble, now preserved at Norsk Folkemuseum as a national monument.
