The largest city park in the world is Nordmarka in Oslo, Norway with an area of 21,441 hectares (53,550 acres).
Oslo is the capital and most populous city in Norway. It constitutes both a county and a municipality. Founded in the year 1040, and established as a “kaupstad” or trading place in 1048 by King Harald III, the city was elevated to a bishopric in 1070 and a capital under Haakon V around 1300.
Personal unions with Denmark from 1397 to 1523 and again from 1536 to 1814 reduced its influence. After being destroyed by a fire in 1624, during Fredriksten’s siege, the city was moved closer toward Akershus Fortress while Christian IV of Denmark built his castle in Christiania in 1631, naming it after himself. The city was renamed Kristiania in 1877 by the Norwegian king, but it remained a separate municipality. In 1925 the city of Oslo became a recognized entity from the surrounding municipality.
A city park is a relatively small area of land within the urban development boundaries that normally has some natural vegetation or landscaped areas. City parks are designed to provide an escape from urban living while supporting activities, relaxation and recreation for city dwellers.
City Park will usually have large open grassed areas for sports use, some more formalised or lightly structured leisure time facilities including picnic spots or seating, children’s play equipment and in most cases some form of waterways with fishing opportunities. It may also include substantial natural woodland on steep slopes which helps with drainage Within cities certain canals are maintained as a “city canal” providing boating opportunities in the heart of the city away from river traffic.
