Work is already under way on the first phase of the scheme, which includes the earthworks and fencing of the site.

The $200m project, near Riyadh on the highway to Mecca, is being carried out in three phases and should be completed in three years.

The local Omrania & Associates is the project manager. It is working in collaboration with the UK landscape-design firm Barton Willmore.

Riyadh Municipality is the client.
