(FILES) This file photo taken on March 31, 2018 shows a man standing outside of the Qasr al-Farid tomb (The Lonely Castle) carved into rose-coloured sandstone in Madain Saleh, a UNESCO World Heritage site, near Saudi Arabia's northwestern town of al-Ula. Citizens from 49 countries are now eligible for tourist visas online or on arrival to Saudi Arabia, thanks to a landmark decision enacted last month, relaxing rules that had largely restricted visits to business travellers and Muslim pilgrims, with the authorities banking on large cities like the capital Riyadh and the western Red Sea port of Jeddah through large-scale investments, including in entertainment.
