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.
Parks and open spaces in Oslo
The organisation Selskapet for Christiania Byes Vel concentrated on creation of public parks as one of its main priorities during its first fifty years of existence. At the bridge Nybrua crossing Akerselva the organisation erected the city's first outdoor monument in 1833, with a surrounding park. Bankplassen was laid out with the city's first bed of flowers in a public park (around 1860). Trees were planted around Oslo Cathedral and Trefoldighetskirken, and the organisation managed to stop construction at Kontraskjæret. Selskapet for Christiania Byes Vel did also organize planting of trees along various streets, among them Grønlandsleiret, the road from Nybrua to Tøyen, Drammensveien and Rådhusgata. Some of the trees are still standing across Kontraskjæret.
