Riyadh’s largest mosque, the monumental Al Rajhi Grand Mosque, is one of the capital city’s most important Islamic institutions. The Grand Mosque is used as a place of worship, with an 18,000-person capacity in the men’s hall and a 2,500-person capacity in the women’s area, as well as a spot for community events. It houses two libraries and an educational center, and Friday prayers are translated into seven languages and shown on digital screens for people with hearing loss.
Visitor information: Non-Muslims are not permitted inside, but it’s worth stopping to admire the impressive exterior architecture, which glows a radiant orange when lit up at night.
