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.
Stortorvet
It was officially inaugurated during the autarchic times, in 1736. A town market was held here until 1889. Marketing still exists, but has largely been moved to Youngstorget. The building that houses the restaurant Stortorvets Gjæstgiveri is a Norwegian Cultural Heritage Site. Other buildings surrounding the square are business buildings such as GlasMagasinet and the main entrance of the Oslo Cathedral.
