Officials at CaixaForum said this comprehensive exhibition of Saudi Arabian pre- and post-Islamic antiquities has been the most popular exhibition to take place at the cultural center. “We have organized many exhibitions in the past, but the Kingdom’s archaeology and history exhibition is different and has attracted a great crowd,” said a CaixaForum spokesperson.  The touring exhibition, which has been to the Louvre and will make its way to Russia in April and Germany in October, features more than 300 archaeological pieces that offer for the first time an insight into Saudi Arabia’s rich historical past. The exhibition will also move to the US, though dates have yet to be announced.  The exhibition was inaugurated by Prince of Asturias Felipe de Borbón, heir to the throne of Spain, Saudi Commission of Tourism and Antiquities Chairman Prince Sultan bin Salman and Saudi Ambassador to Spain Prince Saud bin Naif. More than 100,000 people visited the exhibition when it was taking place at the Louvre, which closed in September.
