RIYADH—Western tourists, a rarity in Saudi Arabia, visited last weekend under a new visa system, as one of the world’s most inaccessible countries tries to open up its society and diversify its economy away from oil.
Thousands of fans flocked to Riyadh’s historic Diriyah district for Formula E, a motorsports tournament using electric vehicles, and concerts including performers David Guetta and Black Eyed Peas.
