Since 2004 a high quality restoration of the Jahan Nama garden has been underway. This large walled garden has existed since at least the 13th century CE. Much of the present design may be 18th century. In a classic Persian garden arrangement, four broad avenues, bordered with orange trees, cypresses and roses converge on an octagonal stone pavilion at the centre. This 18th century pavilion contains an internal fountain pool from which, once restoration is complete, water will flow down steep chadars to pools on each side. In the centre of one of the four avenues from the central pavilion is a long rill, lined with 64 fountains, which stretches nearly to the garden wall. The number 8 is a theme: 8 cypresses on each of the main paths, 8 sections to the long rill, 8 fountains to each section etc. Some very old cypresses survive. There are large areas of colourful planting in geometric flower beds yellow and purple pansies, red, purple and white stock. A pergola is being developed over one avenue path. Many benches are provided for visitors. In April the air is heavy with the scent of orange blossom. Beyond the dark cypresses lining the arcaded boundary walls are views to the rocky Zagros mountains - a nearby hill is topped by the cupola of a dervish shrine.
