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.
Wessels plass
Originally on the site was a knoll with a house surrounded by a garden. The Parliament of Norway Building was completed in 1866, ad in 1873 Oslo municipality bought the knoll. It was demolished around 1880 to give room for a park-like square. Named Stortingspladsen ('The Storting Square'), it was given its current name in 1891. It was named after Johan Herman Wessel, and a bust of him was raised here in 1891. A statue of Johan Sverdrup was raised in 1964. Under the square is a walking tunnel between the Parliament of Norway Building and office buildings across the street.
