The monumental complex at Caserta, created by the Bourbon king Charles III in the mid-18th century to rival Versailles and the Royal Palace in Madrid, is exceptional for the way in which it brings together a magnificent palace with its park and gardens, as well as natural woodland, hunting lodges and a silk factory. It is an eloquent expression of the Enlightenment in material form, integrated into, rather than imposed on, its natural setting.

The property includes five aflaj irrigation systems and is representative of some 3,000 such systems still in use in Oman. The origins of this system of irrigation may date back to AD 500, but archaeological evidence suggests that irrigation systems existed in this extremely arid area as early as 2500 BC. Using gravity, water is channelled from underground sources or springs to support agriculture and domestic use. The fair and effective management and sharing of water in villages and towns is still underpinned by mutual dependence and communal values and guided by astronomical observations. Numerous watchtowers built to defend the water systems form part of the site reflecting the historic dependence of communities on the aflaj system. Threatened by falling level of the underground water table, the aflaj represent an exceptionally well-preserved form of land use.

Threatened by falling level of the underground water table, the aflaj represent an exceptionally well-preserved form of land use.

The property includes five aflaj irrigation systems and is representative of some 3,000 such systems still in use in Oman. The origins of this system of irrigation may date back to AD 500, but archaeological evidence suggests that irrigation systems existed in this extremely arid area as early as 2500 BC. Using gravity, water is channelled from underground sources or springs to support agriculture and domestic use. The fair and effective management and sharing of water in villages and towns is still underpinned by mutual dependence and communal values and guided by astronomical observations. Numerous watchtowers built to defend the water systems form part of the site reflecting the historic dependence of communities on the aflaj system.
