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.
Allotment (gardening)
There are 13 allotment gardens in Norway, with around 2000 allotments. The oldest, Etterstad Kolonihager, dates to 1908. The largest, Solvang Kolonihager, has around 600 allotments and is in Oslo, close to the woods and Sognsvann lake. The allotment gardens are quite popular, and there can be a waiting list of 10 and in some cases even 20 years.
