Like the Xian City Wall, this new structure, we name the Five Climates Crossing will mark the centre of the park and simultaneously act as a connector, linking the Entrance Square on the north, Chang’an Park in the middle and the viewing tower on the south. Within the crossing, the green house is arranged linearly as five different episodes of climates zones, allowing visitors to move sequentially from one green house to another whilst maintaining visual connection to the outside.
