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 Public Library
Oslo Public Library (officially called in Norwegian "Deichmanske bibliotek", Deichman Library), is the municipal public library serving Oslo, Norway and is the country's first and largest library. It employs over 300 people and has over 20 branches throughout the city. Registered users may use the library every day, even when it is not staffed, from 7am to 11pm. It is also possible to borrow and return books when the library is not staffed. One of the most prized books in the library's collection is the Vulgate bible of Aslak Bolt (1430–1450), Norway's only preserved liturgical handwritten manuscript from medieval times.
