The under-construction Makkah Royal Clock Tower is set to become the world’s second tallest building, topped by a clock six times bigger than London’s Big Ben.

The tower will boast 662 meters of concrete structure and a 155-meter crescent-topped metal spire. Combined, the two parts of the tower in Makkah will be only roughly 11 meters shorter than Dubai’s Burj Khalifa, the world’s tallest tower at 828 meters.

Even the concrete section of the Makkah Royal Clock Tower will be taller than the current second tallest building in the world, the 508-meter Taipei 101 in Taiwan. The first part of the hotel is scheduled to open by the end of June, while the clock will begin operating at the end of July. – AFP
