Algeria has inaugurated a gigantic mosque on its Mediterranean coastline after years of political upheaval transformed the project from a symbol of state-sponsored strength and religiosity to one of delays and cost overruns.Built by a Chinese construction firm throughout the 2010s, the “Great Mosque of Algiers” features the world’s tallest minaret, measuring at 869 feet (265 meters). The third largest mosque in the world and largest outside Islam’s holiest cities, its prayer room accommodates 120,000. Its modernist design contains Arab and North African flourishes to honor Algerian tradition and culture as well as a helicopter landing pad and a library that can house up to 1 million books.
