By the 1990s, the Dome of the Rock was beginning to suffer damage again due to both environmental conditions and frequent Israeli police sound bombs. This could be seen on both the interior and exterior. In 1992, King Hussein sold his house in London for $11.636 million in order to pay for the 1994 restorations to the Dome of the Rock. Under King Hussein’s instructions, Jordan's Ministry of Awqaf and Islamic Affairs commissioned professionals to undertake the job of gilding the dome with around 1,200 copper and nickel plates painted with 24 carat gold, as well as rebuilding the roof supports, repairing the basic structure of the building and fireproofing of the Dome from the inside.
