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 City Hall
Oslo City Hall is built of red brick and has two towers, one 63 meters tall and other 66 meters tall. The bricks used are larger than what was typical at the time of construction, but are roughly the same size as bricks used in the middle ages. The bricks - measuring approximately 27,5 x 13 x 8,5 cm - were produced by Hovin Teglverk in Oslo. The eastern tower has a set of 49 bells. Various events and ceremonies take place in the building, including the Nobel Peace Prize ceremony which takes place every December.
