Isana Royal Outer Garden

The Royal Outer Garden of Isana, often known simply as the Royal Garden, is a large park in the north of the city of Isana, near the Risevan Royal Palace. It occupies an area of around 2.1 square kilometres, which is around three quarters of the total area of the Royal Gardens.

The Royal Outer Garden was previously undifferentiated from the Inner Garden until 1843, when by decree of Queen Niseina III this area was opened to the public. From 1843 to 1924 a fee was charged for admission, the proceeds going to the maintenance of the park itself; after that, however, the park was placed along with most other city parks under the governance of the Isana Parks and Public Spaces Department, and admission became free. It is also well known for being the site of the Risevan Botanical Studies Institute, one of the foremost botanical research institutes in the world.
