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 Central Station
Oslo Central was built on the site of the older Oslo East Station (", ), the combining of the former east and west stations being made possible by the opening of the Oslo Tunnel. Oslo Central has nineteen tracks, thirteen of which have connections through the Oslo Tunnel. The station has two buildings, the original Oslo East building and the newer main building for Oslo Central. Each building houses a large shopping centre. The square in front of the station is called Jernbanetorget.
