Construction of The World's Largest Clock - Mecca Clock Tower

It is a construction project full of superlatives: the world’s largest tower clock in Mecca, the Holy City of Islam. The building at the center of the sacred site breaks over 30 world records; its giant clock face is 43 meters in size, the minute hand measures 23 meters in length and the clock drives weigh 21 tons a piece. Put together it is an engineering masterpiece, 35 times larger than Big Ben and adorned in over 98 million glass mosaic tiles with 24-carat gold leaf. By night over two million LEDs illuminate the tower clock making it legible from distances of over eight kilometers.
